How many cubes each of side 2cm are needed to make a large cube with side 20 cm ?
Answers
Answer:
Volume of cube with side 20cm= (side)^3
= (20)^3cm^3
=8000cm^3
Volume of cube with side 2cm= (side)^3
= (2)^3cm^3
= 8cm^3
The number of cubes of side 2 cm that can be drawn out a cube of side 20cm can be calculated as:
Number of cubes
= volume of cube of side 20cm / volume of cube of side 2 cm
= 8000cm^3/ 8cm^3
=1000
Thus 1000 cubes of side 2 cm can be drawn out of a cube of side 20cm.
Answer:
Volume of cube with side 20cm= (side)^3
= (20)^3cm^3
=8000cm^3
Volume of cube with side 2cm= (side)^3
= (2)^3cm^3
= 8cm^3
The number of cubes of side 2 cm that can be drawn out a cube of side 20cm can be calculated as:
Number of cubes
= volume of cube of side 20cm / volume of cube of side 2 cm
= 8000cm^3/ 8cm^3
=1000
Thus 1000 cubes of side 2 cm can be drawn out of a cube of side 20cm.
