Volume of pyramid: 1/3*8squared*3 = 64 cubic cm
There are quite a few ways you could find the height of a square pyramid. You could measure the sides for example.
The simplest way is to measure it using a metric measure tape. An alternative is to measure your height in inches and multiply the answer by 2.54
It takes more centimeters. One decimeter is ten centimeters.

It is: 1/3*64*3 = 63 cubic cm
Volume of a pyramid = 1/3*base area*height Height of a pyramid = (3*volume)/base area
The surface area of the pyramid is superfluous to calculating the slant height as the slant height is the height of the triangular side of the pyramid which can be worked out using Pythagoras on the side lengths of the equilateral triangle: side² = height² + (½side)² → height² = side² - ¼side² → height² = (1 - ¼)side² → height² = ¾side² → height = (√3)/2 side → slant height = (√3)/2 × 9cm = 4.5 × √3 cm ≈ 7.8 cm. ---------------------------- However, the surface area can be used as a check: 140.4 cm² ÷ (½ × 9 cm × 7.8 cm) = 140.4 cm² ÷ 35.1 cm² = 4 So the pyramid comprises 4 equilateral triangles - one for the base and 3 for the sides; it is a tetrahedron.
