Answer:
842 pounds
Explanation:
Given in the question,
dimension of the garage is 35'' by 22'' by 18''
Total gravel need to be filled
L x W x H
35'' x 22'' x 18''
13860 in³
1 in³ = 0.000578704 ft³
13860 in³ = 13860 * 0.000578704 ft³
= 8.0208 ft³
Given that gravel is 105 pounds per cubic foot
so,
105 x 8.0208
842.18793
≈ 842 pounds
