Polly saves her coins in a cube-shaped coin bank. Her coin bank is 7 inches wide and 7 inches tall. What is the volume of Polly's coin bank?
The volume of a cube is found by multiplying the length, width, and height together.
In this case, since the coin bank is cube-shaped, the length is also 7 inches.
So the volume = 7 inches x 7 inches x 7 inches
Simplifying, we get:
V = 343 cubic inches
Therefore, the volume of Polly's coin bank is 343 cubic inches.
To find the volume of a cube-shaped coin bank, you need to multiply the length, width, and height of the cube. Since the coin bank is 7 inches wide and 7 inches tall, the length of each side of the cube is also 7 inches.
Therefore, the volume of Polly's coin bank can be calculated as:
Volume = Length × Width × Height
= 7 inches × 7 inches × 7 inches
= 343 cubic inches
So, the volume of Polly's coin bank is 343 cubic inches.
