Question

Arnie keeps his pet snake in an open-topped glass cage. The outside of the cage is 73 cm long, 60 cm wide, and 38 cm high. The glass used to make this cage is 0.5 cm thick. What is the inside volume of the cage?

Answer 1

1 = 73 - 2*0.5 = 72 cm

w = 60 - 2*0.5 = 59 cm

h = 38 - 1*0.5 = 37.5 cm

V = l × w × h

V = 72*59*37.5

V = 159,300 cm^3
