Question

A rectangular tank has a height of 18 centimeters. The area of its base is 225 square centimeters. Find the volume of the tank.

Answer 1

4050 cm cubed

Explanation:

If the height is 18 cm and the area of the base is 225, we can assume that the length is x, and the width is y. So 18*x*y=area

If the area of the base is 225 cm, we know that x*y=225. And 18*x*y=area. Well, we can say that x=225/y. Substitution method: 18*225/y*y=area. 225/y*y=225, cancelling out. 225*18, then, is 4050 cube cm. I think this is the answer but I’m not really sure... but I hope this helps!

Answer 2

225 x 18 = 4050

base has both length and width. multiply by the height because V=lwh
