Question

A fish tank has the shape of a rectangular prism. It has a length of 2 1/4 meters, width of 7/8 meters, and a height of 1 1/2 meters. What is the volume of the fish tank? 1 31/32 m³ 2 61/64 m³ 4 5/8 m³ 13 5/16 m³

Answer 1

2 61/64 m³

Explanation:

The volume is the product of the linear dimensions. Likely you will need a calculator for this. You may as well have it work the whole problem. (see attachment)

___

If you want to work it by hand, the recommended way is to convert the mixed numbers to improper fractions.

... V = LWH

... V = (2 1/4 m)(7/8 m)(1 1/2 m) = (9/4)(7/8)(3/2) m³

... = (9·7·3)/(4·8·2) m³ = 189/64 m³ = 2 61/64 m³
