In the General case, the base

**of a parallelepiped**is a parallelogram. To find its**area**, using a ruler, make the measurement of the lengths of its sides and a protractor to measure the angle between them. The square*base***of a parallelepiped**is equal to the product of these sides by the sine of the angle between them S=a • b • Sin(α).2

To determine

**the area***of the base***of the box**the other way, measure one side*of the base*, then lower to her height from the vertex, which lies opposite this side. Measure the length of this height. To obtain the area*of the base*find**the area**of a parallelogram by multiplying the length of a side on high, which is omitted S=a • h.3

To obtain the values of area another way to measure the lengths of its diagonals (the distance between opposite vertices), and the angle between the diagonals. The area will be equal to half the product of the diagonals by the sine of the angle between them S=0,5•d1•d2•Sin(β).

For

**a parallelepiped**, which lies at the base of the diamond, it is sufficient to measure the lengths of its diagonals and to find half their work S=0,5 • d1 • d2.5

In the case where the base

**cuboid**is a rectangle, measure the length and width of this geometric figure, and then multiply these values S=a • b. This will be**the area of**its*base*. In the case when the base is square, measure one of its sides and lift in the second degree S=a2.6

If you know the volume

**of the box**, measure its height. To do this, drop a perpendicular from any vertex of the upper*base*onto the plane, which belongs to the lower base. Measure the length of this segment, which is the height**of the box**. If the parallelepiped line (its lateral edges perpendicular to*the base*m), it is enough to measure the length of one of these edges, which equals the height**of the box**. To obtain area*of base*, volume**of a parallelepiped**divide by its height S=V/h.
