Which expression is a perfect cube?

Alex17521 [72]

Answer:

Only $y^{24}$ is a perfect cube.

Step-by-step explanation:

$x^{8}$ is not a perfect cube because 8 is not a multiple of 3.

Now, $y^{24}$ is a perfect cube since 24 is a multiple of 3.

So, $y^{24}$ can be expressed as

$y^{24} =y^{8+8+8}= y^{8} \times y^{8} \times y^{8}= (y^{8}) ^{3}$

Again, $m^{28}$ is not a perfect cube as 28 is not a multiple of 3.

And also $s^{64}$ is not a perfect cube as 64 is not a multiple of 3.

Therefore, only $y^{24}$ is a perfect cube. (Answer)

What is the volume of the square pyramid shown below?

NemiM [27]

Answer: C) $147cm^{3}$

Step-by-step explanation:

First we need to calculate the area of the square base.

This is 7*7 which equals 49 cm squared.

Plug this value into the formula of a square pyramid which will be $V = 49 * \frac{h}{3}$ , now plug in the h, which is 9 cm.

$V = 49 * \frac{9}{3}$

Now solve.

V = 147 cubic cm.
