Knowing the volume of the parallelepiped and the length with the width, you can determine its height.
V = AB * AD * AA1.
150 = 3 * 10 * AA1
AA1 = 150/30 = 5 cm.
Determine the area of the base of the parallelepiped.
Sbn = AB * AD = 3 * 10 = 30 cm2.
Determine the area of the lateral surface of the parallelepiped.
Side = 2 * (AA1 * AD + AA1 * AB) = 2 * (5 * 10 + 5 * 3) = 2 * 65 = 130 cm2.
Determine the total area of the parallelogram.
S floor = 2 * S main + S side = 2 * 30 + 130 = 190 cm2.
Answer: The total area is 190 cm2.
