Question

a fish tank in the shape of a rectangular prism has dimensions of 14 inches,16 inches,and 10 inches. the tank contains 1680 cubic inches of water.what percent of the fish tank is empty? 1)10 2)25 3)50 4)75

Answer 1

2) 25

The total capacity of the tank can be found by finding the volume
V = l x h x w
V = 14 x 16 x 10
V = 2240 cubic inches

The tank only has 1680 cubic inches of water in it

1680/2240 = 0.75
x100% = 75% full

This leaves 25% of the fish tank empty

Answer 2

so
1 find volume
2 divide how much is acuall in there by volume
3. convert to percent


V=LWH
V=14*16*10
V=2240

1680 is actually ful
1680/2240=3/4=0.75
percent means parts out of 100

0.75/1 times 100/100=75/100=75%

total-actuall=emptu
10075=25

answer is 25%
