Dan’s new appliance arrived in a cardboard box in the shape of cube. What is the surface area of the cardboard box? A cube has side lengths of 3 feet. Use the formula S A = 6 s squared, where SA is the surface area of the cube and s is the length of each side.
18 Feet squared
36 Feet squared
54 Feet squared
324 Feet squared

Option C

The surface area of cube is 54 square feet

Solution:

Given that,

Dan’s new appliance arrived in a cardboard box in the shape of cube

A cube has side lengths of 3 feet

The formula to find surface area is:

Where,

s is the length of each side

From given,

s = 3 feet

Therefore,

Thus surface area of cube is 54 square feet

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
