Answer 2

Calculation of the Volume of a Rectangular Prism

To find the volume of a rectangular prism, we need to multiply its length, width, and height. In this case, the aquarium has dimensions of 16/25 m, 17/20 m, and 5/4 m.

The formula for calculating the volume of a rectangular prism is:

Volume = Length x Width x Height

Substituting the given values:

Volume = (16/25 m) x (17/20 m) x (5/4 m)

To simplify the calculation, we can convert the fractions to decimals:

Volume = (0.64 m) x (0.85 m) x (1.25 m)

Now, we can multiply these values to find the volume:

Volume = 0.64 m x 0.85 m x 1.25 m

Calculating this expression gives us the volume of the rectangular prism in cubic meters.

Let's calculate the volume:

Volume = 0.544 m³

Therefore, the volume of the aquarium in the shape of a rectangular prism is 0.544 cubic meters.

Calculation of the Volume of a Cube

To find the volume of a cube, we need to raise the length of one side to the power of 3. In this case, the cube has a side length of 1 1/4 m.

The formula for calculating the volume of a cube is:

Volume = Side Length^3

Substituting the given value:

Volume = (1 1/4 m)^3

To simplify the calculation, we can convert the mixed number to an improper fraction:

Volume = (5/4 m)^3

Now, we can raise this fraction to the power of 3 to find the volume:

Volume = (5/4 m) x (5/4 m) x (5/4 m)

Multiplying these values gives us the volume of the cube:

Volume = (125/64) m³

Therefore, the volume of the aquarium in the shape of a cube is 125/64 cubic meters.

Let's convert this fraction to a decimal:

Volume = 1.953125 m³

Therefore, the volume of the aquarium in the shape of a cube is approximately 1.953 cubic meters.
