Question

Find the total surface area of a rectangular prism with dimensions of 8 ft x 4 ft x 3 ft.

Answer 1

Hi,

To find area of rectangular prism do this.

$a = 8 \\ b = 4 \\ c = 3 \\ s = 2 \times (a \times c) + 4 \times (a \times b) \\ s = 2 \times (8 \times 3) + 4 \times (8 \times 4) \\ s = 2 \times 24 + 4 \times 32 \\ s = 48 + 128 \\ s = 176$

Hope this helps.
