This is my last question in Math. :p

9. Find the volume of a rectangular prism with the following dimensions:

Length = 5 mm
Base = 7 mm
Height = 3 mm

a. 142 mm^3
b. 105 mm^3
c. 126 mm^3
d. 130 mm^3

a rectangular prism is just a box.

volume is length x width x height = 105 mm^3

Oh, okay thanks!

To find the volume of a rectangular prism, we multiply the length, base, and height together.

In this case, the length is 5 mm, the base is 7 mm, and the height is 3 mm. So, the volume can be calculated as:

Volume = Length x Base x Height

Volume = 5 mm x 7 mm x 3 mm

Volume = 105 mm^3

Therefore, the correct answer is b. 105 mm^3.
