The block's dimensions are 9:5:4. Determine its volume if you know that the sum of the longest and shortest edges is 65 cm.

Correct answer:

V =  22500 cm3

Step-by-step explanation:

a:b:c=9:5:4 a=9x b=5x c = 4x  a+c=65 cm 9x+4x = 65 x=65/(9+4)=5 cm  a=9 x=9 5=45 cm b=5 x=5 5=25 cm c=4 x=4 5=20 cm  V=a b c=45 25 20=22500 cm3
