It’s wrong.
The surface area means the area of the outside of the cube.
The area of a square is just width x height. And we are told one of the sides is 5.
A square has all equal sides. So what’s 5x5? then times that by the number of squares
I’ll put the answer in the comments
20/29 is the cosine of theta
The least common multiple would be 209
Answer:
Step-by-step explanation:
One - third = 1/3
then:
one third of a number = a*1/3 = a/3
Then the equation that represents this sentence is:
2 + a/3 = 8
process:
a/3 = 8 - 2
a/3 = 6
a = 6*3
a = 18
Check:
2 + 18/3 = 8
2 + 6 = 8
