we know that
The surface area of a cube is equal to

where
A is the area of one face of the cube
in this problem

Find the surface area

therefore
<u>the answer is</u>
of wrapping paper is needed to cover the box completely
Well the formula for area is A=LxW where L=length and W=width
so A=2.5(1) but this in inches so convert to feet
half inch=15 ft so 2.5 inches=

(15)=5(15)=75 ft
half inch=15 ft so 1 inch=2(15)=30ft
Now we can rewrite our area equation: A=(75ft)(30ft)=2250 ft²
Answer:
b, -19
Step-by-step explanation:
Using the formula to calculate slope:
m = y2 - y1/x2 - x1
m = -9 - (-7)/5 - 6
m = -2/-1
m = 2
