Answers:
Rectangular prism:
Area of base: 16
Height: 5
Answer: 80
Triangular prism:
Area of base: 8
Height: 5
Answer: 40
Explanation:
Rectangular prism
To find the volume of a rectangular prism, all you need to memorize is the formula, which is V = bh. The b stands for base while the h stands for height.
First you need to find the area of the base, to do that you need to multiply the length by the width, which is 4 x 4 = 16
Now you need to multiply the base by the height, which is 16 x 5 = 80
Triangular prism
To find the volume of the triangular prism its the same thing but a different formula. The formula is V = 1/2bh.
First you need to find the base area which is 4 x 4 = 16. The height is 5. Now you solve. 5 x 16 is 80, then you divide 80 in half (1/2) which is 40
