A sand box measures 10 feet long by 8 feet wide by 1 foot deep what area of land must be clearest

What do you mean by "What area of land must be clearest?" Do you mean what land is needed to be cleared? Or how much is needed to fill it up? If that's the case it's 80^3 ft

Answer: 80 cubic feet

Step-by-step explanation:

Hello! Your question was not very clear, but I'm assuming you need to find the volume of the sandbox.

To find volume, you need to multiply height by width by length, which is h*l*w.

Height: 1 foot

Width: 8 feet

Length: 10 feet

V=8*10*1=80 cubic feet.
