Find the volume of the right rectangular prism using cubes with fractional edge lengths. Then use a formula to find the volume.
4/5ft 2/5ft 3/5ft
To find the volume of the right rectangular prism using cubes with fractional edge lengths, we can imagine visualizing the prism as a stacking of individual cubes.
The length of the prism is given as 4/5 ft, the width as 2/5 ft, and the height as 3/5 ft.
We can break each of these dimensions into fractional units, based on the size of a single cube. Let's assume the length, width, and height of each cube to be 1/5 ft.
For the length: 4/5 ft / 1/5 ft = 4
For the width: 2/5 ft / 1/5 ft = 2
For the height: 3/5 ft / 1/5 ft = 3
So, the volume of the right rectangular prism can be calculated by multiplying the number of cubes in each dimension.
Volume = Length x Width x Height = 4 x 2 x 3 = 24
Therefore, the volume of the right rectangular prism using cubes with fractional edge lengths is 24 cubic units.
Alternatively, we can also use the formula for the volume of a rectangular prism:
Volume = Length x Width x Height = (4/5 ft) x (2/5 ft) x (3/5 ft) = (24/125) ft^3
Therefore, using the formula, the volume of the prism is 24/125 cubic feet.
