Question

6. The net of a rectangular prism and its dimensions are shown in the diagram.

Answer 1

Answer:

272 square inches

Step-by-step explanation:

Given

$l = 8$ --- length

$w = 2$ --- width

$h = 12$ ---- height

Required

Determine the total surface area (SA)

This is calculated using:

$SA = 2 * (lw + wh + lh)$

$SA = 2 * (8*2+2*12+8*12)$

$SA = 2 * 136$

$SA = 272$

The total surface area is 272 square inches
