Answer:

272 cm²

Step-by-step explanation:

Surface Area :

  • 2(Length × Width + Length × Height + Width × Height)
  • 2(4 x 4 + 4 x 15 + 4 x 15)
  • 2(16 + 60 + 60)
  • 2(136)
  • 272 cm²

Hey! there

Answer:

  • Surface Area is 272 cm² .

Step-by-step explanation:

In this question we are provided with length 4 cm , height 15 cm and width 4 cm which are basically of a cuboid.

And we are asked to find the Surface Area . For finding surface area of cuboid we need to know its formula . So ,

[tex] \quad \underline{ \boxed{ \frak{Surface \: Area_{(Cuboid)} = 2 ( lw + wh + hl )}}}[/tex]

Where ,

  • l refers to length

  • w refers to width

  • h refers to height

SOLUTION : -

Step 1 : Substituting value of length , width and height in formula :

[tex] \quad \: \longmapsto \: \qquad2((4 \times 4) + (4 \times 15) + (4 \times 15)[/tex]

Step 2 : Solving parenthesis :

[tex]\quad \: \longmapsto \: \qquad2(16 + 60 + 60)[/tex]

Adding 16 , 60 and 60 :

[tex]\quad \: \longmapsto \: \qquad2(136)[/tex]

Step 3 : Multiplying 2 with 136 :

[tex]\quad \: \longmapsto \: \qquad \: \blue{ \underline{ \boxed{ \frak{272 \: cm {}^{2} }}}} \quad \bigstar[/tex]

  • Henceforth , surface area is ❝ 272 cm² ❞.
