*ANSWER PLEASE, NEED HELP* A rectangular pyramid is intersected by a plane to create the frustum shown. If the height of the original pyramid is 14 m, what is the volume of the frustum?

volume of a pyramid is

and frustum is actually, the top portion, i.e. a smaller pyramid taken out of the actual pyramid. so if we subtract that volume from the original volume

the leftover will be the volume of frustum

height of original pyramid is 14 and that of the remaining frustum is 8. so the height of smaller pyramid will be

you can see the respective dimensions marked in the figure.

so the answer will be which is

24*14-80=256 m³

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
