<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.
Answer:
100 ft high
Step-by-step explanation:
We know that Erin, the kite, and her friend create a right triangle since the friend is standing directly under the kite and in front of Erin.
Thus, we can use the Pythagorean theorem to find the height of the kite.
We can let the side the distance be at represents Erin and the kite's distance be EK (aka the hypotenuse), the side that represents Erin and her friend's distance be EF and the side that represents the kite and the friend's distance be KF.
The theorem says that a^2 + b^2 = c^2, where a and b are the two shortest sides and c is the hypotenuse.
We already have the measure of the hypotenuse (260 ft) and one of the shorter sides (240), so we have:
