Question

(use the variable Abase for the area of the base, Aface1 for the area of face 1, and Aface2 for the area of face 2)

A. SA= Abase + 2 x Aface1 + 2 x 4 Aface2
B. SA= 2 x Aface1 + 2 x Aface2
C. SA= Abase + Aface1 + Aface2
D. SA= 2 x Abase + 2 x Aface1 + 2 x Aface2

Answer 1

D. SA= 2 x Abase + 2 x Aface1 + 2 x Aface2
