Question

Each of the four sides of a swimming pool measures 9 meters. The pool is 5 meters deep. How much water will be needed to fill it completely?

A.
45 cubic meters
B.
81 cubic meters
C.
225 cubic meters
D.
405 cubic meters

Answer 1

Answer:

D. 405

Step-by-step explanation:

First, you find the area of the swimming pool without the water. That is 9 x 9 = 81. Then you multiply the area (without water) by 5 to find the area with the water.

Answer 2

Answer:

405 cubic meters (I think...)

Step-by-step explanation:

9 x 9 = 81

81 x 5 = 405
