The fastest way is to just use a scientific calculator.
To do it without a calculator, use prime factorization.
I'll only do the second one which is the answer.
27 x 8
= 3^3 x 2^3 = 6^3
Which is a perfect cube.
Answer:
Step-by-step explanation:
3^2+x^2=6^2
9+x=36
36-9=27
sqrt 27
x=5.2
The surface area of the box is 252in.2 so I guess you should go with 324
Step-by-step explanation:
going around the field one time is walking all 4 sides.
so, 4×13 m
going around the field 5 times is walking all 4 sides 5 times.
that means
5×4×13 m = 20×13 = 260 m
Since all triangles r equal to 180°
123+41= 164
180-164=16
the measure of the third angle of the triangle is 16°
