If the side length of a cube is 40 what is the surface area
Elodia [21]
A cube has 6 sides.

A cube is all made up of squares.

So, we need to find the area of one cube and multiply that by 6.

Length * width= area

40*40= 1,600

Multiply that by 6.

1,600*6= 9600

Whatever the unit is after that: in, feet, cm, m, etc- put that after the number with ^2.

9,600 (the unit) ^2

I hope this helps!

To the Pythagorean Theorem
Aloiza [94]

Answer:

x = 29

Step-by-step explanation:

c^{2} = a^{2} + b^{2}

c^{2} = 20^{2} + 21^{2}

c^{2} = 400 + 441

c^{2} = 841

\sqrt{c^2} = \sqrt{841}

c = 29

Step-by-step explanation:

Given : Process

Step 1: 4x + 2 = 10

Step 2: 4x = 8

To find : Which justification describes the process?

Solution :

From step 1 to step 2, we subtract 2 both sides

Step 1: 4x + 2 = 10

Subtracting 2 both side,

⇒ 4x + 2-2 = 10-2

Step 2: 4x = 8

So, The best justification is 'Using the Subtraction Property of Equality, 2 is subtracted from both sides of the equation'.

Therefore, Option 1 is correct.
