If they are similar, and the second cube's length is 3 times that of the first, then all of the sides are 3 times as large.
To calculate the volume, we multiply the length by the width by the height, each of which is 3 times as big. So, in total, the volume is 27 times larger in the second prism than the first.
So, if the first volume is 30 cubic centimetres, the second one would be 810 cubic centimetres.

Hope I helped! xx

The volume of a cylinder is 300 feet3. Find the volume of a cone and a sphere that have the same height and radius as the cylind

nikitadnepr [17]

The formula of a volume of a cylinder:

$V_{cylinder}=\pi r^2H$

The formula of a volume of a cone:

$V_{cone}=\dfrac{1}{3}\pi r^2H$

Therefore, if a cone has the same radius and height like a cylinder, then the volume of a cone is three times smaller than the volume of a cylinder.

Therefore we have:

$V_{cone}=\dfrac{1}{3}V_{cylinder}\to V_{cone}=\dfrac{1}{3}(300)=100\ ft^3$

The formula of a volume of a sphere:

$V_{sphere}=\dfrac{4}{3}\pi R^3$

If a cone has that same lengths of a radius and a height, then the formula of a volume is:

$V_{cone}=\dfrac{1}{3}\pi r^2r=\dfrac{1}{3}\pi r^3$

If a cone and a sphere have the same radius, then the volume of a sphere is four times greater than a volume of a cone.

Therefore we have:

$V_{sphere}=4(100)=400\ ft^3$
