Find the surface area and volume of a rectangular parallelepiped whose length is 12 cm

Find the surface area and volume of a rectangular parallelepiped whose length is 12 cm, width 7.5 cm and height 10 cm.

Let the length be “a”, width “b”, and height “c”.

The surface area of a rectangular parallelepiped is:

S = (a * b + b * c + a * c) * 2 = (12 * 7.5 + 7.5 * 10 + 12 * 10) * 2 = 285 * 2 = 570cm ^ 2.

The volume of a parallelepiped is equal to the product of its length by width and height:

V = a * b * c = 12 * 7.5 * 10 = 900cm ^ 3.

Answer. The surface area of this rectangular parallelepiped is 570 cm ^ 2, and its volume is 900 cm ^ 3.
