Question

What is the area of the cross section if the length is 12 cm and the width is 10 cm?

120 cm2
1.2 cm2
32 cm2
2 cm2

Answer 1

120 cm²

Explanation:

From the question;

• Length is 12 cm
• Width is 10 cm

We are required to determine the area of the cross section;

• Note that the cross section is the plane of a solid that remains constant through the solid.
• In this case, the cross section is a rectangle whose dimensions are 12 cm by 10 cm.

But Area of a rectangle = Length × Width

Therefore;

Area of cross section = 12 cm × 10 cm

= 120 cm²

Thus, area of the cross section is 120 cm²
