Question

You want to put a 2 inch thick layer of topsoil for a new 13 ft by 27 ft garden. The dirt store sells by the cubicyards. How many cubic yards will you need to order? The store only sells in increments of 1/4 cubic yards.cubic yards:

Answer 1

2 1/4 cubic yards

Explanations:

The formula for calculating the volume of the garden is expressed as:

`V=length* width* height`

Determine the volume of the garden

Volume = 13ft * 27ft * 2/12ft

Volume = 58.5 cubic feet

Convert cubic feet to cubic yards

Recall that 1 cubic yards= 27 cubic feet

Hence:

58.5 cubic feet = 58.5/27 = 2.17 cubic yards

Since the store only sells in increments of 1/4 cubic yards and we can’t buy 0.17 cubic yard of soil, we need to round off to the next number of cubic yards that is exactly divisible by 1/4 to give 2 1/4 cubic yards
