A square pyramid has a height of 6 units and a volume of 70 units3. If a square prism has the same base area and volume as the s
Svetach [21]

Answer:

The height of the prism is h=2\ units

Step-by-step explanation:

step 1

Find the area of the base of the pyramid

The volume of the pyramid is equal to

V=\frac{1}{3}Bh

where

B is the area of the base of pyramid

h is the height of the pyramid

we have

V=70\ units^{3}

h=6\ units^{3}

substitute and solve for B

70=\frac{1}{3}B(6)

70=2B

B=35\ units^{2}

step 2

Find the height of the prism

The volume of the prism is equal to

V=Bh

where

B is the area of the base of prism

h is the height of the prism

we have

V=70\ units^{3}

B=35\ units^{2}

substitute and solve for h

70=35h

h=2\ units

You and your friend are painting the walls in your apartment. You estimate that there is 1000 square feet of space to be painted
leva [86]
After 45 minutes you will have painted 4*45=180 square feet.

so the total number of painted area, y, is:

y=180+x*(3+4) after the 45 minutes

where x is the number of minutes AFTER THE 45 minutes:

if y is 1000 then

1000=180+x*7
820=x*7
x=117.14

so 117 minutes, or one hour and 57 minutes.
