Acandy bar is packaged in a box that has the shape of a triangular prism. the triangular ends of the box each has a base 4 cm long and a height that is 3 cm long. the box is 15 cm long.  what is the volume of the box?   a. 22 cm3   b. 44 cm3   c. 90 cm3   d. 180 cm3

The volume of any prism is B*l, where B is the base area and l is the length. 1) Find the Area of a triangular side. 2) Multiply that area by the length.The volume of any prism is B*l, where B is the base area and l is the length. 1) Find the Area of a triangular side. 2) Multiply that area by the length.
4×3=12
12×15
So the answer is D. 180 cm3

B, 0.4 repeats so it is rational and square root of 16 is 4 so that is rational as well.
