Question

What is the volume if a 3cm hole is cut through a 5cm wood

Answer 1

Answer:

Volume of a Cube (V) = (edge)3 = a3;

where a = edge

Answer 2

The correct question is

What is the volume, if a 3cm hole is cut through a 5cm wood in a cylinder shape with of height of 10cm?

Given:

Diameter of hole, d = 3 cm

Diameter of wood,D = 5cm

Height of cylinder, h = 10cm

To Find:

The volume of the cylinder after the cut portion is removed.

Solution:

The volume of the wood after the cut portion is removed is,

V = π (R²- r²)h

  = π (5²- 3²)10

  = π (25-9)10

  = 502.7 cm³

Therefore, The volume of the cylinder after the cut portion is removed is 502.7 cm³.
