Question

find the surface area of a cuboid if its length is 15 and the breadth is 16 and the height is 12​

Answer 1

${\huge{\underline{\underline{\sf {\mathfrak{Answer}}}}}}$

${\underline{\underline{\rm {Given:}}}}$

• $Length(l)=15$
• $Breadth(b)=16$
• $Height(h)=12$

${\underline{\underline{\rm {Solution:}}}}$

$Surface \ area = 2(lb+bh+hl)$

$Surface \ area = 2(15 × 16 + 16 × 12 + 12 × 15[/[tex]Surface \ area = 2(240 + 144 + 180)$

$Surface \ area = 2(564)$

$\boxed{\implies{\boxed{Surface \ area = 1128 \ units^2}}}$

Answer 2

Answer:

1224

Step-by-step explanation:

Given ,

Length of cuboid = 15

Breadth of cuboid = 16

Height of cuboid = 12

We know that,

Surface area of cuboid = 2lb + 2bh +2lh

                                       = 2(15 x 16) + 2(16 x 12) + 2(12 x 15)

                                       = 2(240) + 2( 192) + 2( 180)

                                        = 480 + 384 + 360

                                       = 1224
