Question

A cube with side lengths measuring 4 inches. The cube was sliced parallel to the base. Identify the cross-section and calculate its area.

Answer 1

The resulting cross section is a square an the area is
`A=16\ in^(2)`

Explanation:

we know that

All the faces of the cube are square with side lengths measuring 4 inches

If the cube was sliced parallel to the base

then

the cross section is a square with side lengths measuring 4 inches

so

The area of a square is

`A=b^(2)`

we have

`b=4\ in`

substitute

`A=4^(2)`

`A=16\ in^(2)`
