clint is covering the sides and top of a box that is .75 feet wide, 13 inches long and 2 inches high with material. how many square inches of materials will clint need?

Respuesta :

Ok, it is asking for the suface area of a rectangular prism - 1 base side.
So lets find the sides. 
2(wl+hl+hw)                      l is length, w is width, h is height
wl + 2hl + 2hw is our formula
0.75 feet is 9 inches
9*(13) + 2(2)(13) + 2(9)(2)
= 117 + 53 + 36
= Your answer is 206

Please award me the brainliest if I am correct. 
Thank You.
