Find the volume of a rectangular prism with the following dimensions length=5 mm width=7 mm height =3 mm
142 mm^3
105 mm^3
126 mm^3
130 mm^3
The volume of a rectangular prism is found by multiplying the length, width, and height.
Volume = 5 mm × 7 mm × 3 mm
Volume = 105 mm^3
Therefore, the volume of the rectangular prism is 105 mm^3. Answer: \boxed{105\text{ mm}^3}.
To find the volume of a rectangular prism, you need to multiply its length by its width and then multiply the result by its height.
So, the volume can be calculated as follows:
Volume = Length x Width x Height
Volume = 5 mm x 7 mm x 3 mm
Volume = 105 mm^3
Therefore, the volume of the rectangular prism with the given dimensions is 105 mm^3. Hence, the answer is option (b) 105 mm^3.
