Question

how many cubic centimetres of metal will be requiredto make a cube weight an edge length 16mm

Answer 1

16mm=1.6 cm.
Volume of cube=1.6×1.6×1.6
=4.096 cubic cm.
Since,4.096 cubic cm of metal will be required.

$<b>$
Side of the cube = 16 mm
As 1 cm = 10mm
$1 \: \: mm = \frac{1}{10} \: cm \\ 16 \: mm = 16 \times \frac{1}{10} \\ = 1.6 \: cm$
Now we know the formula

Volume of the cube = side^3
=
$= (1.6) {}^{3} \\ = 4.096 \: cm {}^{3}$
So 4.096 cubic centimeters are required to make a cube.
