The formula for the volume of a pyramid is V = Bh, where B is the area of the base of the pyramid and h is the height of the pyramid.
The figure below is made of two identical rectangular pyramids. What is the volume of the
entire figure?
8 in.
10 in.
6 in.
10 in.
960 cubic inches
320 cubic inches
480 cubic inches
160 cubic inches

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

answer: 800
