Find the volume and surface area of a pyramid with height 3 2cm and square base sides all 6 cm length?

SOURCE: surface area of a rectangular prism whose length

Since the 'base' and 'top' of any prism have the same shape, the surface area can be found by

• surface area of prism = 2 * area of base + perimeter of base * H

• surface area = 2LW + 2(L+W)H
• = 2 * 7 * 4 + 2*(7+4)*5
• = 56 + 2 * 11 * 5
• = 56 +110
• = 166 sq cm

You need 5 isosceles triangles with a base of 30 mm. To get the height of the triangles (perpendicular to the 30 mm bases) you need to calculate the apothem of the pentagon (assumed to be regular).

If you cut the pyramid by a plane passing through its apex, the center of the base-pentagon,and the midpoint of one side, the plane figure created by the three points (apex, center, and midpoint) is a right triangle. The legs are the apothem, and the altitude of the pyramid. The hypotenuse is the slant height of the pyramid, and is thus the height of the triangles in the development. pyramid (60 mm) form.
Use the Pythagorean Theorem to find that slant height.
s^2=a^2+h^2.

SOURCE: A block of wood shaped like a rectangular prism. The area of the base is 96 square centimeters. The volume of the block is 1440 cubic centimeters. What is the height in centimeters?

Divide 1440 cubic centimeters by 96 centimeters to get 15 centimeters.
