<h2>1210 cubic feet</h2>
Step-by-step explanation:
Initial dimensions of the storeroom were
length,
width and
height.
The room is in the shape of a cuboid. Volume of a cuboid =
, where
are the length, width and height of the cuboid.
So, Volume of storeroom initially = 
Finally, the length was increased to
and width to
.
Final volume of storeroom = 
Increase in volume = 
∴ 1210 cubic feet of storage was added.
I believe the first quartile would be 24 and the third would be 8. Sorry if this wasn't correct. I haven't done this in a while.
Hope it helps
To find his age 4 years ago, you need to subtract 4 from his current age.
His current age is Y, so his age 4 years ago is: y - 4
Do you mean greater than or least than?
If you're not sure then here are them in greater and least than,
2.647 < 2.648 (Least than)
2.648 > 2.647 (Greater than)
