Answer:

SA = 2520 ft^2

Step-by-step explanation:

a = 21ft

b = 29ft

c = 20ft

h = 30ft

SA = 2 $A_{B}$ + (a+b+c)h

$A_{B}$ = s(s﹣a)(s﹣b)(s﹣c)

s = $\frac{a + b + c}{2}$

SA= ah + bh + ch + $\frac{1}{2}$ $\sqrt{-a^4 + 2(ab)^2 + 2(ac)^2 - b^4 + 2(bc)^2 - c4}$

SA= (21 * 30) + (29 * 30) + (20 * 30) +

$\frac{1}{2}$ $\sqrt{-(21)^4 + 2(21 * 29)^2 + 2(21 * 20)^2 - (29)^4 + 2(29 * 20)^2 - (20)^4}$

SA = 2520 ft^2

Can someone help with this question?

ivann1987 [24]

You solve an expression for a variable if that variable sits alone on one side of the equation, and everything else is on the other side.

So, our goal is to leave $h$ alone on the right hand side, and move everything else to the left.

So, we start with

$V = \dfrac{1}{3}s^2h$

We multiply both sides by 3:

$3V = s^2h$

We divide both sides by $s^2$

$\dfrac{3V}{s^2} = h$

To compute the required height, simply plug in the values:

$\dfrac{3\cdot 400}{10^2} = \dfrac{3\cdot 400}{100} = 3\cdot 4 = 12$
