George has just purchased a small rectangular fish tank that holds 837 milliliters of water. The tank has a width of 6.2 cm and a height of 9 cm.
What is the length of the fish tank?

15 cm

Step-by-step explanation:

Area = Length ⋅ Width ⋅ Height

let's set:

Area: 837

Length: X

Width: 6.2 cm

Height: 9cm

837 = X ⋅ 6.2 ⋅ 9

First multiply 6.2 and 9 to get 55.8

Next divide 837 by 55.8 and you get 15

therefore, the length (x) is equal to 15

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
