To find the length of the side, will take the under root of the area. So, the side will be :
c) 24.4 cm
Answer:
-1/60
Step-by-step explanation:

= 
=
(find LCM of demoninators)
= 
= 
= -1/60
The average is (0.76+0.88) / 2 = 1.64 / 2 = 0.82
<u>Given</u>:
Given that the side length of the cube is 1.8 cm
We need to determine the lateral surface area of the cube.
<u>Lateral surface area of the cube:</u>
The lateral surface area of the cube can be determined using the formula,

where a is the side length.
Substituting a = 1.8 in the above formula, we get;

Squaring the term, we get;

Multiplying, we get;

Thus, the lateral surface area of the cube is 12.96 cm²
Answer:
x=1
Step-by-step explanation:
We wanna have the same amount on both sides
There are 3 circles on the left and 7 circles on the right. There are also 4 triangles. Turn into numbers...
4x+3=7
4x=7-3
x=1
We can check by substituting one
7=7
