In order to find the volume of a rectangular parallelepiped, you need to multiply the length of the parallelepiped by the width and by the height.
V = 12 cm * 7.5 cm * 10 cm = 900 cm³.
In order to calculate the surface area of a rectangular parallelepiped, you need to find the sum of the areas of the parallelepiped’s faces.
S = (12 cm * 7.5 cm + 12 cm * 10 cm + 7.5 cm * 10 cm) * 2 = (90 cm² + 120 cm² + 70 cm²) * 2 = 560 cm².
Answer: the volume of the parallelepiped is 900 cm³, the surface area is 560 cm².
