<u>The answer is 8.13</u>
Step-by-step explanation:
Let's elaborate the expression:
5 (1 3/8 plus 1.2)3 / .5 plus 10
5 (1.375 + 1.2)³ / 0.5 + 10
5 * 2.575³/ 10.5
85.369297/10.5
8.13

Answer: 3
Step-by-step explanation:
The top and bottom have area (2.4 ft)² = 5.76 ft².
The sides have area (4*2.4 ft)*(3.4 ft) = 32.64 ft².
The the total area is (2*5.76 +32.64) ft² = 44.16 ft². All but the bottom area is then 44.16 ft² -5.76 ft² = 38.40 ft².
The ratio (all but bottom area)/(total area) is then
38.40/44.16 ≈ 87.0%
