5. A cylindrical pipe is placed in a rectangular trench that is 5m x 4m

and 2.5m deep, is placed across the shorter side of the trench.

5.1 How much volume of cement will be needed to cover this hollow

pipe?

and 2.5m deep, is placed across the shorter side of the trench.

5.1 How much volume of cement will be needed to cover this hollow

pipe?

Answer:The volume (density) of cement that will be needed to cover this hollow pipe is:

= 50,000 kg/m³

Step-by-step explanation:Length of a cylindrical pipe = 5m

Width of the cylindrical pipe = 4m

Depth of the cylindrical pipe = 2.5m

The cubic meters of the cylindrical pipe = 5 * 4 * 2.5 = 50m³

1 cubic meter is equal to 1,000 kilogram

Therefore, the volume (density) of cement that will be needed to cover this hollow pipe is:

= 50 * 1,000

= 50,000 kg/m³
