Question

- 3.4 The rectangular box has the length of 8x² and the breadth of 6x² - 4x

Answer 1

The formula for calculating the area of a rectangle is expressed as A = lw. The area of the box is 48x^4 - 32x^3 cubic units

Area of a rectangle

The formula for calculating the area of a rectangle is expressed as:

A = lw

Given the following parameters

• length l = 8x²
• breadth w = 6x² - 4x

Determine the area

Area = (8x²)6x² - 4x

Area of the box = 48x^4 - 32x^3

Hence the area of the box is 48x^4 - 32x^3 cubic units
