rectangular prism of length 45 centimeters, width
30 centimeters, and volume 81,000 cubic centimeters.
What is the height, in centimeters, of the box?
A. 75
B. 60
C. 48
D. 27
E. 18

Answer 1

V=81 000cm³

V=Ab *h

Ab=L*w

Ab=45*30
Ab=1350cm²

V=1350*h

1350*h=81 000

h=81 000/1 350
h=60cm answer variant b)

Answer 2

Volume = (length) x (width) x (height)

81,000 = (45) x (30) x (height)

Height = (81,000) / (45 x 30) = 60 cm
