Answer 1

Question:

If the dimensional of the cuboid are 3

cm ,4 cm 10 cm the its surface area is ?

To find:

$\star \: Surface \: area \: of \: Cuboid$

Answer:

$Option\: \underline{\:\bold{ b)}\:is\:the\: answer.\:}$

$Surface \: area \: of \: Cuboid \: is \: \underline{ \: \underline{ \: \sf \pink{\bold{164{cm}^{2}}} \: } \: }$

Given:

✶ Dimensional of the cuboid are 3 cm ,4 cm ,10 cm.

$l = 3cm, \: w = 4cm, \: h = 10cm$

Step-by-step explanation:

$\boxed{ Surface \: area \: of \: Cuboid= 2lh + 2wh + 2lw }$

$\implies 2(3)(10) + 2(4)(10) + 2(3)(4)$

$\implies 2(30) + 2(40) + 2(12)$

$\implies 60 + 80 + 24$

$\implies \boxed{164{cm}^{2}}$

$\therefore Surface \: area \: of \: Cuboid \: is \: \underline{ \: \bold{164{cm}^{2}} \: }$

Formula used:

$\bigstar SA\: of \: Cuboid= 2lh + 2wh + 2lw\: sq.units$

$Where,$

$l \: is \: Length$

$w \: is \: width$

$h \: is \: height$

More information:

✯ A cuboid is a three-dimensional shape with a length, width, and a height.

✯The cuboid shape has six sides called faces.

✯The cuboid has 12 edges.
