What is the height of a cubiod whose cross-sectional area is 48cm square and volume is 216m cube

1 answer

We need to convert the volume to cubic centimeters since the cross-sectional area is given in square centimeters.

1 m = 100 cm

Volume = 216 m^3 = 216000000 cm^3

Let the height be h, length be l, and width be w of the cuboid.

Cross-sectional area = lw = 48 cm^2

Since the cross-sectional area is equal to length times width, we can express the length in terms of the width:

l = 48/w

Volume = lwh = (48/w)wh = 48h cm^3

We can now substitute the volume value:

48h = 216000000

h = 4500000 cm

Therefore, the height of the cuboid is 4500000 cm or 45 km.
