The perimeter of the base of right prism whose base is an equilateral triangle is 30 cm. If its whole surface area is 150+50√3 cm^2
cm2, find the height of the prism.
Perimeter of the base = 30 cm.
So, side of the base = 10 cm.
Whole surface area of the prism = perimeter of base *height + 2 * area of base
h = 5 cm
