Question

Find the surface area of the prism.

Answer 1

`SA=232(cm^(2) ).`

Explanation:

1. Gather the measures (it doesn't matter what you call each measure for the case of rectangular prisms).

Lengh (L): 2 cm

Width (W): 8 cm

Height (H): 10 cm

2. Write the formula for the surface area of a rectangular prism.

`2(WL+HL+HW)`

3. Substitute the gathered measures into the formula and calculate.

SA= Surface Area.

`SA= 2((8)(2)+(10)(2)+(10)(8))\\ \\SA=232(cm^(2) )`
