A typical stone on the lowest level of the Great Pyramid in Egypt was a rectangular prism 5 feet long by 5 feet high by 6 feet deep and weighed 15 tons. What was the volume of the average stone? How much did one cubic foot of this stone weigh?

The volume of the average stone was ____ cubic feet. One cubic foot of this stone weighed ____ton or ___pounds.

Answer 1

Volume = 150 ft³

Weight = 0.1 tons or 200 pounds

Explanation:

Find the volume with the formula V = Bh

V = 30(5)

V = 150 ft³

Set up a proportion to find the weight of one cubic foot

`(15)/(150)` =
`(x)/(1)`

x = 0.1

Answer 2

150 ft^3

.1 ton or 200 lbs

Explanation:

The volume is given by

V = l*w*h

V = 5*5*6

V = 150 ft^3

To find how much 1 ft^3 weighed take the weight and divide by the volume

15 tons / 150 ft^3

.1 ton / 1 ft^3

1 ft^3 weights .1 ton

We know that 1 ton = 2000 pounds

.1 ton = 200 pounds
