5*5*6 = 150cm2
side is 5, side area is 5*5, there are 6 sides
The diagonal of a square is the product of its side or edge and √2.
The face diagonal of a cubical box is edge√2.
Find the edge/side of the cube if its diagonal is 5√2 cm:
Diagonal = side√2
5√2 = side√2
side = (5√2)/(√2)side = 5 cm.
Find the total surface area of the cube whose faces are 6:
Total surface area = 6(side)²
Total SA = 6(5 cm)²
Total SA = 6(25 cm²)Total SA = 150 cm²
Step-by-step explanation: because (3x-10)2=-14x
Just do the 3-10=7
7x2 = - 14
Why negative because negative ten is higher that positve 3
So basically the answer is -14x
Here you go! enjoy.
