Complete question:

A cube has a side length of 1/3 inch.It would take _ blocks with a side length of 1/6 inch to fill the cube.

B)It would take _ blocks with a side length of 1/9 inch to fill the cube.

Answer:

a) 8 blocks

b) 27 blocks

Step-by-step explanation:

Here we need to find the volume of the cube and volume of the block.

To find volume of the cube, let's use the formula :

V = a³

Here a = $\frac{1}{3}$

Therefore,

V = $(\frac{1}{3})^3$

V = = $\frac{1}{27}$

Volume of the cube is $\frac{1}{27}$

To find volume of the block, let's use the formula:

V = a³

V = $(\frac{1}{6})^3$

V = $\frac{1}{216}$

To find the number of blocks, let's divide the volume of block from the volume of cube.

Therefore,

= $\frac{\frac{1}{27}}{\frac{1}{216}}$

$= \frac{1}{27} * 216$

= 8

It would take 8 blocks with a side length of 1/6 inch to fill the cube.

B) Here we also need to find the volume of the cube and volume of the block.

To find volume of the cube, let's use the formula :

V = a³

Here a = $\frac{1}{3}$

Therefore,

V = $(\frac{1}{3})^3$

V = = $\frac{1}{27}$

Volume of the cube is $\frac{1}{27}$

To find volume of the block, let's use the formula:

V = a³

V = $(\frac{1}{9})^3$

V = $\frac{1}{729}$

To find the number of blocks, let's divide the volume of block from the volume of cube.

Therefore,

= $\frac{\frac{1}{27}}{\frac{1}{729}}$

$= \frac{1}{27} * 729$

= 27

It would take 27 blocks with a side length of 1/9 inch to fill the cube.

How do I do this qn?

denis-greek [22]

You can take the log of the left and right hand side, and then apply the <span>logarithm rules:

log(a</span>ˣ) = x·log(a)
log(ab) = log(a) + log(b)

log(9^(x-1) * 2^(2x+2)) = log(6^(3x))
log(9^(x-1)) + log(2^(2x+2)) = 3x log(6)
(x-1) log(9) + (2x+2) log(2) - 3x log(6) = 0
x(log9 + 2log2 - 3log6) = log9 - 2log2
x = (log9 - 2log2) / (log9 + 2log2 - 3log6)

simplifying by writing log9 = 2log3 and log6 = log2+log3

x= 2(log3 - log2) / (2log3 + 2log2 - 3log2 - 3log3) =
x= -2(log3 - log2) / (log3 + log2) = -2 log(3/2) / log(6)

So 6^x = 4/9
