Question

I need help! The cube's original side length is 4.5cm. What is the area of a cross section sliced perpendicular to the base?

Answer 1

Answer:

${20.25 \: cm}^{2}$

Step-by-step explanation:

If the cross section is cut perpendicular to the base, it will be like an upside down T where the _ is the base and the | is the cross section.

This means the measurements of the cross section will be the width × height.

Because this shape is a cube, we know these measurements will both be 4.5cm.

4.5 × 4.5 = 20.25

The area of the cross section is 20.25 square centimeters.
