Answer:

a=\frac{2A}{h}-b

Step-by-step explanation:

we know that

The formula to calculate the area for a trapezoid is equal to

A=\frac{1}{2}(a+b)h

where

a and b are the parallel bases

h is the height of trapezoid

A is the area

<em>Solve for a</em>

That means ----> isolate the variable a

Multiply by 2 both sides to remove the fraction in the right side

2A=(a+b)h

Divide by h both sides

\frac{2A}{h}=a+b

Subtract b both sides

\frac{2A}{h}-b=a

Rewrite

a=\frac{2A}{h}-b

Find the volume of a square pyramid with a base area of 18 in.² and a height of 6 in
Ludmilka [50]

ANSWER

36 cubic inches.

EXPLANATION

The volume of a square pyramid is calculated using the formula:

V =  \frac{1}{3}  {l}^{2}  \times h

where l² is the area of the base and h= 6 inches is the height of the square pyramid.

We substitute the values into the formula to get,

V =  \frac{1}{3} \times  18 \times 6 \:  {in}^{3}

We simplify to get:

V =  6 \times 6  =3 6 {in}^{3}

Therefore the volume of the square pyramid is 36 cubic inches.
