respectively. Find its surface area.




please answer me​

Answer 1

Answer:

630cm³

Step-by-step explanation:

15×12×2+12×5×2+5×15×2=total surface area of cuboid

Answer 2

Answer:

Surface Area is 630$cm^{2}$

Step-by-step explanation:

∵ Formula of Surface Area of Cuboid : 2(lb+bh+hl)

∵ Length = 15cm

∵ Breadth = 12cm

∵ Height = 5 cm

∴ S.A = 2(15*12 + 12*5 + 15*5)

S.A = 2 ( 180 + 60 + 75 )

S.A. = 2(315)

==> S.A. = 630$cm^{2}$
