1 |
Problem |
The object has dimensions of 4 cm in length, 8 cm in width, and 4 cm in height. Find the area of one of its faces, which is a 2D shape consisting of only length and width. |
|
2 |
Step |
The side length of an object is given. |
4 cm |
3 |
Step |
Given the width of an object, |
8 cm |
4 |
Step |
Now, we find the area of the object for 2D shape. |
|
5 |
Formula |
Area of rectangle is |
length \$\times\$ width |
6 |
Step |
Now plug the values into the formula |
A = \$4 \times 8\$ A = 32 |
