A rectangular prism has a height of 20 cm, length of 7 cm and width of 5 cm.

Use the volume formula to find the volume of this prism.

The formula for the volume of a rectangular prism is:

V = length x width x height

Substituting the given values, we get:

V = 7 cm x 5 cm x 20 cm

Multiplying these values, we get:

V = 700 cm³

Therefore, the volume of the rectangular prism is 700 cubic centimeters.
