You have 275 square inches of wrapping paper. Do you have enough wrapping paper to wrap the gift box shown?
1 answer:
The surface area of the box is bigger than the <em>surface area</em> of the available wrapping paper. <em>Thus, you don't have enough wrapping paper to wrap the gift box.</em>
The given parameters;
- area of the wrapping paper available, A = 275 square inches
- volume of the gift box, V = 343 in²
First, determine the length of each side of the box;
The length of each side is represented with x;
x³ = 343
Second, find the surface area of the box;
surface area of the box, A = 6x²
A = 6(7)²
A = 294 in²
The surface area of the box is bigger than the <em>surface area</em> of the available wrapping paper. Thus, you don't have enough wrapping paper to wrap the gift box.

Both Rhianna and Christopher were correct as they took different reference angles.
Step-by-step explanation:
Step 1:
The value of the tan of a reference angle is calculated using the above formula.
The hypotenuse is the longest side of the triangle is always opposite the right angle of the triangle.
In this triangle, the hypotenuse is the side measuring 5 units.
Step 2:
When the reference angle is A, the opposite side measures 3 units and the adjacent side measures 4 units.
So
When the reference angle is C, the opposite side measures 4 units and the adjacent side measures 3 units.
So
So both Rhianna and Christopher were right as they took different reference angles i.e. A and C.
