Question

a rectangle prism is 4 units high, 2 units wide, and 6 units long. what is its surface area in square units?

Answer 1

SA: 2(w × l + h × l + h × w)    w = 2, l = 6, h = 4

SA: 2(2 × 6 + 4 × 6 + 4 × 2)

SA: 2(12 + 24 + 8)

SA: 2(36 + 8)

SA: 2(44)

SA: 88

hope that helps, God bless!

Answer 2

Surface area of the rectangle prism is 88 sq. units.

Given:

height of the rectangle prism (h) = 4 units

width of the rectangle prism (w) = 2 units

length of the rectangle prism (l) = 6 units

Recall:

Formula for surface area of a rectangle prism is:

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

Plug in the values:

$SA = 2(6\times 2 +2\times4 +6\times4)\\SA = 2(12 + 8 + 24)\\SA = 2(44)\\SA = 88$

Therefore, the surface area of the rectangle prism is 88 sq. units.
