The length of a rectangular parallelepiped is a cm, width b cm and height c cm.Find the volume, surface area

The length of a rectangular parallelepiped is a cm, width b cm and height c cm.Find the volume, surface area and the sum of the lengths of all edges of this parallelepiped if: c) a = 0.67, b = 0.95, c = 4.24.

The volume of a rectangular parallelepiped is calculated by the formula:

V = a * b * c.

Let’s find this value, provided that the measurements of such a figure are 0.67 cm, 0.95 and 4.24 cm:

V = 0.67 * 0.95 * 4.24 = 2.7 cm³.

The sum of the lengths of all edges is determined by the formula:

L = 4 * (a + b + c) = 4 * (0.67 + 0.95 + 2.7) = 4 * 4.32 = 17.28 cm.

Let’s calculate the surface area:

S = 2 * (ab + bc + ac) = 2 * (0.67 * 0.95 + 0.95 * 4.24 + 0.67 * 4.24) = 2 * (0.64 + 4.03 + 2.84) = 2 * 7.51 = 15.02 cm².
