Answer:
To fill the sandbox, she would need 15 cubic feet.
Step-by-step explanation:
To find the volume of a box, multiply all of its dimensions together.
6ft * 5ft * 1/2ft = 15ft^3
So, since she bought 20 cubic feet of sand, she should have enough with 5 cubic feet left over.
The answer is 1. That was easy because any number to the power of 0 is just 1.
3/2.52 is 1.5
In other words it is 1 1/2
