Amy and alex are making models for their science project. both the models are in the shape of a square pyramid. the length of the sides of the base for both the models is 8 inches. amy’s model is 5 inches tall and alex’s model is 3 inches tall. find the difference in volume of the two models.

The difference in volume of the two models is

Step-by-step explanation:

we know that

The volume of a square pyramid is equal to

where

b is the length of the side of the square base

h is the height of the pyramid

step 1

Find the volume of Amy's model

we have

substitute

step 2

Find the volume of Alex's model

we have

substitute

step 3

Find the difference in volume of the two models

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
