Question

A pedestal on which a statue is raised on is a rectangular concrete solid measuring nine

feet long, nine feet wide, and six inches high. How much is the cost of the concrete in the

pedestal, if concrete costs $70 per cubic yard?

Answer 1

The cost of the rectangular concrete solid is $104.87

Explanation:

If the pedestal on which a statue is raised on is a rectangular concrete solid measuring nine feet long, nine feet wide, and six inches high, the volume of the rectangular concrete solid will be expressed as shown;

Volume of the rectangular concrete solid = Length * Width * Height

Given Length = 9ft, Width = 9ft and Height = 6inches

Converting all the units to yards

Given 1ft = 0.333yard

Length = 9 * 0.333 = 2.997yards

Width = 9* 0.333 = 2.997yards

Also given 1inch = 0.0278yard

Height = 6 * 0.0278yards = 0.1668yards

Volume of rectangular concrete solid in cubic yards = 2.997*2.997*0.1668

Volume of rectangular concrete solid in cubic yards = 1.4982cubic yards

If concrete costs $70 per cubic yard, the cost of the rectangular concrete solid will be 1.4982 *$70 = $104.87
