Answer:
13 cm
Step-by-step explanation:
The base of the right pyramid is the square of the side that is 27 cm long. If the volume of pyramid is 3159 cm³, what is the height?
Area of base of pyramid = a² = 27² cm²
Volume of pyramid, V
V = 3159 cm³ = ⅓a²h
h = (3 × 3159)/a² = (3 × 3159)/27² = (3 × 117)/27 = 117/9 = 13 cm
