Half of 30 students would be 15 (30 / 2 = 15)

One third of 15 is 5 (15 / 3 = 5)

15 students have cellphones, 5 of them are allowed to use social media.

The square pyramid has a volume of 486 cubic inches. What is the value of x?
Softa [21]

Volume of square pyramid can be calculated by the formula :

V=a^{2}\frac{h}{3}

a is the length of base and h is the height of the pyramid.

In the given figure a= x in.and h = \frac{1}{4}  x in.

Volume of pyramid given V =486 cubic inches.

Substituting these values in volume of pyramid we have:

486= x^{2}  \frac{x}{4} ÷ 3

Or 486=\frac{x^{3}}{4}  x\frac{1}{3}

486= \frac{x^{3}}{12}

Multiplying both sides by 12

5832 =x^{3}

18^{3}  =x^{3}

Or x= 18 in.
