Question

It would be awesome for some help! :3 Johnny Uses a wheelbarrow to move planting soil to a delivery truck. The volume of planting soil fits in the wheelbarrow measures 2 feet by 3 feet by 1.5 feet. The truck measures 11 feet by 8 feet by 6 feet. Johnny puts planting soil in the truck until it's 70% full. What is the minimum number of times Johnny needs to use the wheelbarrow until the truck is 70% full?

Answer 1

We are given with
dimensions of wheelbarrow = 2ft x 3ft x 1.5 ft
dimensions of truck = 11 ft x 8 ft x 6 ft

The volume of the wheelbarrow is 2(3)(1.5) = 9 ft3
The volume of the truck is 11(8)(6) = 528 ft3
70% of this is
528 ft3 (0.7) = 369.6 ft3
Dividing this by the volume of the wheelbarrow
369.6 ft3 / 9 ft3 = 41.07
He would need to use the wheelbarrow 42 times.
