Richard has just purchased a small rectangular fish tank that holds 1,170 milliliters of water. The tank has a length of 15 cm and a height of 12 cm. What is the width of the fish tank?

the width of the fish tank is 6.5 cm

Step-by-step explanation:

The formula for determining the volume of a rectangular tank is expressed as

Volume = length × width × height.

From the information given,

Volume of water in the fish tank = 1,170 milliliters

Length of tank = 15 cm

Height of tank = 12 cm

Width of tank = W

Since 1 cubic cm = 1 milliliters, it means that

15 × 12 × W = 1170

180W = 1170

W = 1170/180

W = 6.5 cm
