Equilateral Triangle Height = side * square root (3) / 2 =

12 * 0.8660254038 = 10.3923048454

Triangle Area = 12 * 10.3923048454 * .5

= 62.3538290724 

Pyramid Area = 62.3538290724 * 4 sides =

 249.4153162896

Can some one solve this (squar roots)

Inessa05 [86]

Answer:

2 $\sqrt{6}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying the radicals

$\sqrt{96}$

= $\sqrt{16(6)}$

= $\sqrt{16}$ × $\sqrt{6}$ = 4 $\sqrt{6}$

$\sqrt{24}$

= $\sqrt{4(6)}$

= $\sqrt{4}$ × $\sqrt{6}$ = 2 $\sqrt{6}$

Thus

$\sqrt{96}$ + 2 $\sqrt{6}$ - 2 $\sqrt{24}$

= 4 $\sqrt{6}$ + 2 $\sqrt{6}$ - 4 $\sqrt{6}$ ← collect like terms

= 2 $\sqrt{6}$
