Visualize and Find the surface area of a rectangular prism MATH 6 Quarter 3 Week 7 Billy De Belen

hello guys welcome back to my channel in this session we will study the surface area of solid figure quarter three week one solid figures okay example let us visualize what is the so-called surface area the measure of this side now what is the surface area of this give repair so find the area of rectangle length times wheel the length is 2.5 feet and the width is 2 feet so 2.5 times 2 is equal to 5 square feet and that is the surface area of this give repair solid figure solid figures not this is rectangular solid or rectangular prism not where in the height of this rectangular prism is 4 centimeters let us visualize the surface area of this rectangular prism and surface how to compute the surface area of this rectangular prism this is face of the triangle rectangular prism lateral face lateral face nato is four times two is eight centimeter times centimeter is square centimeter so the area of this lateral face is eight square centimeters surface area if this side or lateral face the lateral area is eight square centimeter this four times one length length times weight four times one is four square centimeters eight square centimeters four square centimeter the tall this one this face is another eight square centimeter and this one is also four square centimeter this phase because the measure of this side is one centimeter and the height is four centimeter four times one is equal to four so the surface area of this lateral face and the other one is eight plus eight sixteen square centimeters sixty nausea and this one is 4 square centimeter 16 plus 420 and this is another 4 square centimeters or 1 0 times 4 is 4 square centimeters four or eight plus eight sixteen plus four twenty plus four is twenty-four into pieces malignant on the bodies is the base of this rectangular prism and this is another base there are two bases and this is two no two times one the area of this face is two square centimeter and this is also two square centimeter valley two plus two by four square centimeters 28 eight plus eight sixteen plus four twenty plus another four twenty four plus 2 26 another 2 28 therefore the surface area of this figure is 28 square centimeters now here is the formula in finding the surface area of rectangular prism stands for surface area stands for lateral area plus 2b and stands for base lateral area it is equal to times eight where is the perimeter of the base polygon of the eights perimeter of the base centimeter two this is another two this is one this is two plus two is four plus one is five plus one is six so the lateral area of this or the perimeter again the perimeter of this base is six centimeters lateral area know unlateral area times perimeter is six times eight or height six times height four is equal to twenty-four or nothing lateral area is equal to perimeter two three four five six or valley six centimeters perimeter therefore the lateral area is equal to six times four 24 centimeter times centimeter is equal to square centimeters operating square centimeter therefore the lateral area is 24 square centimeters surface area surface area no is equal to and 24 square centimeter plus two or you base nothing base nut and two and one the area is two times one is two square centimeter that is the area of the base of this rectangular prism 2 times 1 2 square centimeters times 2 square centimeters surface area is equal to 24 square centimeters plus 2 times 2 is 4 centimeters surface area now is equal to 24 plus 4 is 28 square centimeters odibatama 28 square surface area is equal to 28 square centimeters therefore this is the formula in finding the surface area of rectangular prism thanks for watching bye
