82

Step-by-step explanation:

Vertical rectangle:

A = bh

A = (5)(10)

A = 50

Horizontal rectangle:

h = 10 - (3 + 3)

h = 4

A = bh

A = (8)(4)

A = 32

Combined:

50 + 32

82

Answer:

[tex]A=82 meters^2[/tex]

Step-by-step explanation:

First we will split the shape into two rectangles.

Now that it is in two separate peaces, solve each one individually

Remember   [tex]A = l*w[/tex]

[tex]10*5=50[/tex]

[tex]8*4=32[/tex]

Finally add the two areas together

A cube has a surface are of 54. What's the volume?


A. 36

B. 27

C. 18

D. 64
80 points!!

Answers

Given Information :

Surface area of cube = 54 sq. units

To find :

Volume

Calculation :

We know that,

[tex]\bigstar \: \boxed{\sf {Volume_{(Cube)} = (\ell)^3}} \\ [/tex]

l = length of side

Let's find out the side first. We know that,

[tex]\bigstar \: \boxed{\sf {T.S.A_{(Cube)} = 6\ell^2}} \\ [/tex]

According to the question,

[tex] \longmapsto \sf {54 = 6\ell^2 } [/tex]

[tex] \longmapsto \sf {\dfrac{54}{6} = \ell^2 } [/tex]

[tex] \longmapsto \sf {9 = \ell^2 } [/tex]

[tex] \longmapsto \sf {\sqrt{9} = \ell } [/tex]

[tex] \longmapsto \sf \red{3 \: units = \ell } [/tex]

Now, calculating volume :

[tex]\bigstar \: \boxed{\sf {Volume_{(Cube)} = (\ell)^3}} \\ [/tex]

→ Volume = l × l × l

→ Volume = 3 × 3 × 3

→ Volume = 27
