Answer:
The cost of the rectangular concrete solid is $104.87
Step-by-step 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
