The front of the box is a rectangle, with a width (or length in this case) and height. The area of the square (surface area of the front of the box) is found by multiplying the width and height.
To calculate the area of the front surface of a box, you multiply the length by the height, which is option (c). The formula is A = l × h, and this applies to finding the area of a rectangle.
To calculate the area of the front surface of a box, you multiply the length by the height. This calculation gives you the area of a rectangle, which corresponds to the front face of a box. If the length is l and the height is h , the formula for the area is simply A = l × h.
For example, if a box has a length of 5 units and a height of 3 units, the area of the front surface would be 5 × 3 = 15 square units.
The other options provided like adding the length to the height or multiplying then dividing by two are incorrect for calculating the area.
Knowing the correct formula is essential, but it can also be helpful to understand that the area represents the amount of space on the flat surface, which is found by multiplying the two-dimensional measurements together.
To find the area of the front surface of a box, multiply the length by the height. The correct answer is option (C): multiply the length by the height. The formula for area is A = l × h .
