Question

L
The length breath and height of a
cuboid que 15cm, 10 CMand 20 cm respectively
find its total surface area​

Answer 1

Answer:

total surface area

2(length×breadth+breadth×height+height×length)

=2(15×10+10×20+20×15)sq cm

=2(150+200+300)sq cm

=2(650) sq cm

=1300 sq cm

Answer 2

Answer:

1300

Step-by-step explanation:

Cuboid dimensions : -

Length ( l ) = 15 cm

Breadth ( b ) = 10 cm

Height ( h ) = 20 cm

Total Surface Area = 2(lb + bh + hl)

= 2 [ (15)(10)  +  (10)(20)  +   (20)(15)  ]

2 [ 150 + 200 + 300 ]

= 2 [ 650 ]

= 1300
