Question

Find the volume of the rectangular prism

Answer 1

Answer :

7 1/2 cubic units

Note :
2 1/2 = 2 + 1/2 = 4/2 + 1/2 = 5/2

1 1/2 = 1 + 1/2 = 2/2 + 1/2 = 3/2

Formula:
Volume of a rectangular prism = base × height
__________
base = (2 1/2) × 2 = (5/2) × 2 = 5
Therefore
The Volume of the rectangular prism = 5 × (1 1/2) = 5 × (3/2) = 15/2 = (14+1)/2 = 14/2 + 1/2 = 7 + 1/2 = 7 1/2

Answer 2

To find the volume of a rectangular prism:

⇒ must know the formula

`Volume = length*width*height`

⇒ basically all the side lengths multiplied together

Solve:

`Volume = 2(1)/(2)*2*1(1)/(2) =(5)/(2)*2*(3)/(2) =(15)/(2)units^3`

Answer: The volume is 15/2 cubic units
