A solid right pyramid has a square base with an edge length of x cm and a heigt of y cm. Which expression represents the volume of the pyramid?
A. 1/3x2y cm3
B. 1/2xy2 cm3
C. 1/3xy cm3
D. 1/2x2y cm3
This is all the info I am given HELP

Answer :

Answer:

Option B ⇒ Area of base of each pyramid :

[tex](\frac{x}{4})^2 in^2[/tex]

Option A ⇒ Volume of pyramid :

[tex]\frac{1}{3} x^{2} \cdot y [/tex]   cm3

Step-by-step explanation:

One side of tile consists of 4 pyramids and since length of whole tile is x,

So, the base length of each pyramid = [tex]\frac{x}{4}[/tex]

⇒ Area of base of each pyramid = side²

⇒ Area =

[tex](\frac{x}{4})^2 in^2[/tex]

Volume of square based pyramid :

[tex]=(Area of base )\cdot \frac{h}{3}\\=\frac{x^2}{3} cm^3[/tex]

For 1. The correct Option is B

For 2. The correct option is A

Answer:

the answer is A!
