Answer:
252
Step-by-step explanation:
Formula
2wl + 2lh + 2hw=
2( 12 x 6) + 2( 12x3) + 2 ( 3x 6)
2(72) + 2(36) + 2(18)=
144 + 72 + 36= 216 + 36
252
Step-by-step explanation:
l = 12 in
w = 6 in
h = 3 in
<h3>S. Area = 2 (lw + lh + wh)</h3>
= 2 (12 × 6 + 12 × 3 + 6 × 3)
= 2 (72 + 36 + 18)
= 2 × 126
= 252 in^2
