Question

Daisy wants to fill one-third of her sandbox with sand. The sandbox is 5.2 feet long, 4 feet wide and 1.5 feet high. Sand is sold for $1.30 per cubic foot. How much will it cost Daisy to fill one-third of her sandbox? $

Answer 1

The dimensions of the sandbox are 5.2 ft, 4 ft, and 1.5 feet.
The volume is
5.2*4*1.5 = 31.2 ft³

One-third of the volume is
31.2/3 = 10.4 ft³

One cubic foot of sand sells for $1.30. The cost to fill one-third of the sandbox is
(1.30 $/ft³)*(10.4 ft³) = $13.52

Answer: $13.52
