Hoochie [10]

Answer:

11 inches

Step-by-step explanation:

Let the level of ground level be g

On first day, amount of snow melted by 3 inches

So, level of ground melted= (g- 3) inches

Next day, amount of snow melted by 8 inches

So, level of ground level melted = (g- 3-8 )inches

Hence, total change in the ground level = ( g- 11) inches

Hence, amount of snow on ground level melted by 11 inches

Hence, the correct answer is 11 inches

A solid right pyramid has a square base with an edge length of x cm and a height of y cm. Which expression represents the volume

solniwko [45]

Answer:

Thus, volume of pyramid = $\frac{1}{3}x^2y$ cm³

Step-by-step explanation:

Given: A solid right pyramid has a square base with an edge length of x cm and a height of y cm.

We have to choose from the given options an expression for the volume of the pyramid.

Volume of pyramid = $\frac{1}{3}\times Area\ of\ base \times height$

Since base is a square with edge length x cm.

Area of square = (side)² = x²

Thus, volume of pyramid = $\frac{1}{3}x^2y$ cm³
