To calculate the volume of the solid and how much does monument weighs.
Answer to Problem 34E
The volume of the monument is 41.67 feet3& the monument weighs 7084 pounds.
Explanation of Solution
Given information: The side length(a) of pyramid is 5 feet, height(h) of pyramid is 5 feet. 1 cubic foot of marble weighs about 170 pounds.
Formula used:
Calculation:
Substituting the values of edge & height
Hence the volume of the monument is,
41.67 feet3
Since weight of 1 cubic foot of marble= 170 pounds
Therefore, weight of 41.67 cubic foot of marble = 41.67×170
Weight of the monument is,
7083.9 ˜7084 pound
