A cube is a three dimensional figure with all edges equal.

So it length = width = height

The formula to find the volume of a cube is

V = s³.

Here s represents the length of the cube.

In the given question we are given s = 2.1 cm

So the volume of the cube shall be

V = 2.1³

V = 2.1 × 2.1 × 2.1

V = 9.261 cm³

Now this can be rounded off to two decimals as 9.26 cm³

The volume of the required cube is 9.261 cm³ 0r 9.26 cm³

C. Line m is a perpendicular<br> bisector. If EG=12 and FG=5,<br> of then how long is:
strojnjashka [21]

Answer:

EF = 13

GH = 5

EH = 13

Step-by-step explanation:

Given

The attached figure

EG = 12

FG = 5

Solving (a): EF

Since m is a perpendicular bisector, then <EGF and <EGH are right-angled.

So, EF will be calculated using Pythagoras theorem which states:

EF^2 = EG^2 + FG^2

EF^2 = 12^2 + 5^2

EF^2 = 144 + 25

EF^2 = 169

Take the positive square roots of both sides

EF = \sqrt{169

EF = 13

Solving (b): GH

Since m is a perpendicular bisector, then GH = FG

FG = 5

GH = FG

GH = 5

Solving (c): EH

Since m is a perpendicular bisector, then EH = EF

EF = 13

EH = EF

EH = 13

the diagram shows the width of a rectangle 1/3 cm and is area 1/5 cm square. find the length of the rectangle
Anna35 [415]
Area= length(width)
1/5=1/3(length)
Length= 1/5(3/1) or 1/5 divided by 1/3
Length= 3/5 cm
Therefore, the length of the rectangle is 3/5 cm.
Hope this helps!
