Explanation

To find the volume of a rectangular box, we use the formula:

Volume=Length×Width×Height

Given the dimensions of the box:

Length (𝐿) = 10 cm

Width (𝑊) = 15 cm

Height (𝐻) = 20 cm

Plug these values into the formula:

Volume=10cm×15cm×20cm

Volume=10×15×20

Volume=150×20

Volume = 3000cm^3

So, the volume of the rectangular box is 3000cm^3

 .

Explanation

The formula for the volume of a rectangular prism is:

Volume = Length × Width × Height

In this case, the length, width, and height are all 3 cubic inches, so:

Volume = 3 × 3 × 3 = 27 cubic inches

Therefore, the volume is 27 cubic inches.
