Question

A water tank is in the shape of a rectangular prism. The tank measures 20 yards by 5 yards by 9 yards. If Ruthie filled half of the tank with water, how many yards full is the tank?

A.900 cubic yd

B.225 cubic yds

C.450 cubic yds

D.500 cubic yds

Answer 1

C. 450 yd^3

Explanation:

V... volume of a prism

a = 20 yd

b = 5 yd

c = 9 yd

Vw... Volume of water

Vw = V/2

Vw = (abc)/2

Vw = 900yd^3/2

Vw = 450yd^3

Answer 2

C, 450 cubics yds because 20 x 5 x 9 equals 900. 900 divided by two (half) is 450
