Which expression represents the height of the pyramid? StartFraction 3 V Over y squared EndFraction units (3 V minus y squared)
maxonik [38]

Answer:

Height = 3v/y² units

StartFraction 3 V Over y squared EndFraction units

Step-by-step explanation:

The volume of a solid right pyramid with a square base is v units3 and the length of the base edge is y units. which expression represents the height of the pyramid? units (3v – y2) units (v – 3y2) units units

Volume of a solid right pyramid = 1/3 × area of the base × height

Volume of a solid right pyramid = v units³

Area of the base = y² unit²

Volume of a solid right pyramid = 1/3 × area of the base × height

v = 1/3 × y² × height

Height = v ÷ 1/3 × y²

= v × 3/1y²

= (v × 3) / y²

= 3v / y²

Height = 3v/y² units

StartFraction 3 V Over y squared EndFraction units
