Answer:

The answer is 20,600,000,000

Step-by-step explanation:

Basically, for a positive exponent, you'll need to move the decimal to the right, and here, the exponent is 10, so the first 2 movements are whats already after the decimal, and 8 more 0's after that

if that makes sense

Answer: C can complete the work in 12 days.

Step-by-step explanation:

Alright, lets get started.

Given that, A and B can separately do a piece of work in 24 days and 16 days respectively.

It means, in 1 day, A can complete the part of work : $\frac{1}{24}$

It means, in 1 day, B can complete the part of work : $\frac{1}{16}$

As they both worked together for 6 days,

in 6 days, A can complete the part of work : $6*\frac{1}{24}=\frac{1}{4}$

in 6 days, B can complete the part of work : $6*\frac{1}{16}=\frac{3}{8}$

So, together they had completed the work : $\frac{1}{4}+\frac{3}{8}=\frac{5}{8}$

So remaining work will be : $1-\frac{5}{8}$

So remaining work will be : $\frac{3}{8}$

Now this remaining work is done by A and C together.

Suppose C alone can do this work in C days.

So in 3 days, A and C completed the rest work :

$3 \times(\frac{1}{24}+\frac{1}{C})=\frac{3}{8}$

$\frac{1}{24}+\frac{1}{C}=\frac{1}{8}$

$\frac{1}{C}=\frac{1}{8}-\frac{1}{24}$

$\frac{1}{C}=\frac{1}{12}$

$C=12$

Hence C can complete the work in 12 days. : Answer

Step-by-step explanation:

We have the rectangular prisms.

The formula of a volume of a rectangular prism is:

$V=lwh$

l - length

w - width

h - height

==========================================

Look at the picture.

Two congruent rectangular prisms 14cm × 3cm × 5cm.

$V=2(14\cdot3\cdot5)=420\ cm^3$

One rectangular prism 15in × 4in × 6in and next 7in × 4in × 3in:

$V=15\cdot4\cdot6+7\cdot4\cdot3=360+84=444\ in^3$

One rectangular prism 10cm × 3cm × 2cm and next 4cm × 3cm × 4cm:

$V=10\cdot3\cdot2+4\cdot3\cdot4=60+48=108\ cm^3$

One rectangular prism 10m × 3m × 6m and next 8m × 3m × 6m:

$V=10\cdot3\cdot6+8\cdot3\cdot6=180+144=324\ m^3$
