Answer:
a. 80
b. 2250
c. 180
d. 320
e. 269.255
f. 2,143.573
g. 433.333

j. 144
Step-by-step explanation:
a. rectangular prism
In finding the volume, we need to multiply the length, width, and height of the prism.
2 cm × 10 cm × 4 cm = 80
b. rectangular prism
In finding the volume, we need to multiply the length, width, and height of the prism.
15 cm × 15 cm × 10 cm = 2250
c. triangular prism
In finding the volume, we need to multiply the base of the triangle, height of the triangle, and length of the prism. Afterwards, we divide the number we will get by 2.
= 180
d. rectangular pyramid
In finding the volume, we need to multiply the length of the base, width of the base, and height of the pyramid. Afterwards, we divide the number we will get by 3.
= 320
e. cylinder
In finding the volume, we need to multiply pi(3.14), square of the radius, and height of the cylinder.
3.14 × × 7m = 269.255
f. sphere
In finding the volume, we need to multiply pi(3.14), cube of the radius, and 4. Afterwards, we divide the number we will get by 3.
= 2,143.573
g. rectangular pyramid
In finding the volume, we need to multiply the length of the base, width of the base, and height of the pyramid. Afterwards, we divide the number we will get by 3.
= 433.33
h. cylinder
In finding the volume, we need to multiply pi(3.14), square of the radius, and height of the cylinder.
3.14 × × 17.9 cm = 269.255
i. cone
In finding the volume, we need to multiply pi(3.14), square of the radius, and height of the cone. Afterwards, we divide the number we will get by 3.
= 37.68
j. triangular prism
In finding the volume, we need to multiply the base of the triangle, height of the triangle, and length of the prism. Afterwards, we divide the number we will get by 2.
= 144
