Maija is building a square sanbox wiht 2 feet long.she wants to put sand 1.55 feet deep in the box.How much sand should Maija order?

Question

 I need help on this problem.

Answer 1

What we're looking at is the volume of a prism. the length and width are each 2 ft., while depth is 1.55 ft.

That means our equation is 2 ft * 2 ft * 1.55 ft = V

4 ft² * 1.55 ft = V

6.2 ft³ = V

 

So Maija needs 6.2 cubic feet.
