The formula of the volume of a pyramid is 1/3BH, where B represents the area of the base of the pyramid and H represents the hei

zysi [14]

Answer:

It depends on the relation between the heights of both pyramids

Step-by-step explanation:

We know the volume of a pyramid of base b and height h is

$V=\frac{1}{3}bh$

If the volume of the pyramid A is 3 times the volume of the pyramid B, then

$\frac{1}{3}b_ah_a=3*\frac{1}{3}b_bh_b=b_bh_b$

Which means

$b_ah_a=3*b_bh_b$

If we knew both heights are the same, we could conclude that

$b_a=3*b_b$

In which case the base of the pyramid A would be greater than the other base

But if, for example, the height of the pyramid A is 3 times the height of the other height, then

$3*b_a=3*b_b=>b_a=b_b$

Both bases would be the same.

If we choose that

$h_a >3*h_b$

it would mean

$b_a$

In which case the base of the pyramid A would be less than the other base

So the answer entirely depends on the relation between the heights of both pyramids

Can you please solve 2 and 3

Murrr4er [49]

I’m pretty sure that I’m pretty sure that question 2 is 1 minute and 40 seconds. And for number 3 I got B. 0.25 because if you look at where the line makes a direct cross between pounds and dollars that first one is 8 pounds for 2 dollars. If you divide 8 by 2 you will get 0.25. Hope this helped :)
