The base area = 3 x 4 = 12 square cm. The volume = 1/3 height x base area = 1/3 x 5 x 12 = 20 cubic cm.
11cm x 5cm = 55cm2.

Volume_cube = side x side x side = 5cm x 5cm x 5cm = 125 cm3

5cm to the 3rd power = 5cm x 5cm x 5cm = 125cm3 (or 125 cubic centimeters)
The base area = 3 x 4 = 12 square cm. The volume = 1/3 height x base area = 1/3 x 5 x 12 = 20 cubic cm.
1/3 x 12 = 4(1/3 x 12) / 2 = 2
11cm x 5cm = 55cm2.
60cm 12 multiplied by 5cm is the same as 6 multiplied by 10cm, as 12 divided by 2 equals 6, and 5cm multiplied by 2 equals 10cm. 6 multiplied by 10cm equals 60cm. That theory is called doubling and halving.

half of 8 is 4, 4 x 3 = 12, 12/4 = 3.
3 x 4 x 5 = 60cm3
Volume_cube = side x side x side = 5cm x 5cm x 5cm = 125 cm3
