*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 $\frac{lbh}3$

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 $14-8=6$

you can see the respective dimensions marked in the figure.

so the answer will be ${12\times 6\times 14 \over 3} - { 4\times 10 \times 6 \over 3}$ which is

24*14-80=256 m³

n = - $\frac{13}{8}$

Step-by-step explanation:

Given

- 8n = 13 ( divide both sides by - 8 )

n = $\frac{13}{-8}$ = - $\frac{13}{8}$

52 cm^2

Step-by-step explanation:

Solve by splitting the figures into 2 parts and finding their areas separately:

Rectangle:

8 × 5 = 40

Triangle:

1/2 × b × h = 1/2 × 8 × 3 = 4 × 3 = 12

Total: 40 + 12 = 52

q < 5

Step-by-step explanation:

Since there is an open circle it means there is no equal sign

The line goes to the left so it is less then q < 5
