Question

What is the volume in mL of a cube with each side 80mm long ?

Answer 1

512 mL is the volume of a cube with each side 80 mm long.

Step-by-step explanation:

Side of the cube , a= 80 mm = 8 cm( 1 mm = 0.1 cm)

Volume of the cube ,V=
`a^3`

`V=(8 cm)^3=512 cm^3`

And 1 cubic centimeter is equal to 1 milliliter .

`1 cm^3=1 mL`

Volume of the cube in milliliter = V =
`512 cm^3=512 L`

512 mL is the volume of a cube with each side 80 mm long.

Answer 2

512 mL

Step-by-step explanation:

We are given;

• A cube with a side 80 mm long or 8 cm long

We are required to calculate the volume;

• Volume refers to the amount of space an object occupies.
• To calculate the volume of a cube we get the cube of its side;

• That is, volume of the cube = l³

Therefore;

Volume = (8 cm)³

= 512 cm³

But; 1 cm³ = 1 mL

Therefore, the volume of the cube in mL is 512 mL
