Question

Holly works in a stable. She's throwing straw into a stall that's 12 feet long by 8 feet wide. If she throws 12 cubic feet of straw each minute, how many minutes will it take until the straw in the stall is 2 feet deep?

Answer 1

Firstly, calculate the volume.
V = 12 x 8 x 2 <- (2 because we want 2 feet deep)
= 192 cubic feet
Now, each minute she fills 12 cubic feet.
so minutes to get to 2 feet deep = 192/12 = 16 minutes
