Anna has purchased three gift for her closest friends. She decides to wrap them in holiday paper. How many square inches of wrap
2 answers:
Here the gift is of the shape of cube.
So in order to wrap the gift we need to find the surface area of cube.
The formula to find surface area of cube is given by:
Where a is length of each edge.
So let us find surface area of one cube.
Length of side length (edge) is given as 7 inches.
Plugging this in the formula:
Surface Area of one cube = 294 square inches.
Now Anna purchased Three gifts.
So Surface area of three gifts = 3*294 = 882 square inches.
Answer: Total wrapping paper required by Anna is 882 square inches.

The sum of angles in any quadrilateral, including trapezoid, is 360⁰.
Because we have <span>an isosceles trapezoid, we have 2 angles with measure 135⁰,
and we have 2 equal acute angles with measure x⁰.
So, we can find value of acute angle,
135*2 +2x =360⁰
270+2x=360
2x=360-270
2x=90
x=45⁰
So, acute angles in trapezoid = 45⁰.
From triangle ABC,
angle ACB =90⁰
angle A=45⁰,
so angle ABC= 180-(90-45)=45⁰
Triangle ABC is isosceles triangle,so |AC| = |CB|= 5 in.
So, longer base AA' = 5+4+5= 14 in
Now, we can find area of trapezoid.
shorter base = 4 in
longer base = 14 in
altitude =h = 5 in
Area of trapezoid =(1/2)(base1+base2)*h
Area of trapezoid = (1/2)(4+14)*5= 9*5=45 in²
Answer is 45 in².</span>
