Answer 1

A) the outside of a three-dimensional shape

A) six

Question 3 — 222 square inches
Reason: SA = 2(lw + lh + wh). With l=9, w=3, h=7: SA = 2(27 + 63 + 21) = 2(111) = 222.

Question 4 — 13.5 square meters
Reason: For a cube SA = 6s^2. If s = 1.5 m, SA = 6(1.5^2) = 6(2.25) = 13.5.

Question 5 — 384 square inches
Reason: SA = 6s^2 = 6(8^2) = 6(64) = 384.
