Area = length x width
21 = length x 5
length = 21/5 = 4.2
The length is inversely proportional to the width because as the length increases the width reduces and vice-versa
Answer:
192
Step-by-step explanation:
The volume of a prism is 3 cubic units. Dividing each cube into 1/4 size cubes means each small cube will have 1/64 cubic inches.
This means 64 1/4 cubes fit into 1 cube. So for 3 cubes, 3*64 = 192 cubes.
For this case we must solve the following equation:

Subtracting 2 from both sides of the equation we have:

Equal signs are added and the same sign is placed.

Multiplying by 4 on both sides of the equation we have:

Thus, the solution of the equation is
