Answer:
<h3>The surface area in square meters that Darren has to paint is

</h3><h3>∴

</h3>
Step-by-step explanation:
Given that Darren is painting a wooden block is a rectangular prism
Its length is 12 cm ,width is 9 cm and height is 5 cm
<h3>To find the surface area in square meters that Darren has to paint :</h3>
Let l be the length, w be the width and h be the height
Then l=12 cm , w=9 cm and h=5 cm
The formula for the Surface area is
A=2(lw+wh+hl) square units
Substitute the values in formula we get,
A=2(12(9)+9(5)+5(12))
=2(108+45+60)
=2(213)
=426
<h3>∴

</h3><h3>∴ the surface area in square meters that Darren has to paint is

</h3>
" the product " means multiply
km <== ur expression...which means k * m
Answer:
240000000 times bigger.
If we solve 3x10^8 we get 300000000
Then if we solve for 6x10^7 we get 60000000
Subtract those two using long subtraction to evaluate and we get 240000000
