| The volume of the rectangular parallelepiped is 72 cm3. Width – 4 cm. Length – 6 cm. What will be the volume if the length is increased by 2 cm.
Let’s find the volume of a rectangular parallelepiped if the length is increased by 2 cm.
To do this, we first calculate the height from the volume of the original parallelepiped.
V = a * b * c.
Hence c = V \ a * b.
We substitute. c = 72/4 * 6 = 72/24 = 3 cm.
Now we will increase the length by 2 cm.
6 cm + 2 cm = 8 cm new parallelepiped length.
And we find the volume of the new rectangular parallelepiped using the formula.
V = 4 * 8 * 3 = 96 cm 2.
Answer: the volume is 96 cm 2.
