Asked by Katniss Everdeen

The bases of a right prism are parallelograms with sides a=10 cm, b=6 cm, and altitude of the parallelogram towards side a, ha = 3 cm. Find the surface area of the parallelepiped, if the height of the prism is h=12 cm.
Answered by Steve
the area of each base is just 10*3=30

Then you have four rectangles. Two that are 10x12 and two that are 6x12

Now just add up all those six areas.
