Question

Find the surface area of the space figure represented by the net.

A) 264 in.2
B) 290 in.2
C) 145 in.2
D) 242 in.2

Answer 1

290 in^2.

Explanation:

Adding all the areas of rectangles:

= 11*8 + 11*3 + 11*8 + 11*3 + 3*8 + 3*8

= 290 in^2.

Answer 2

B) 290 in²

Explanation:

Area of a rectangle = length × width

⇒ SA of the net = 2(11 × 8) + 2(11 × 3) + 2(8 ×3)

= 176 + 66 + 48

= 290 in²
