Question

find the total surface area of cuboid whose length is equal to 7.5 breadth equal to 5.2 cm and height is 03 centimetre​

Answer 1

length of cuboid is equal to 7.5

breadth of the cuboid is equal to 5.2

height of cuboid is equal to 3 cm

total surface area of cuboid : 2(lb+bh+hl)

2(7.5*5.2+5.2*3+7.5*3)

answer 154.2

Answer 2

Answer:

length of cuboid:-7.5cm

breadth of cuboid:-5.2cm

height of cuboid:-3cm

here,total surface area of cuboid=2(lb+bh+hl)

2{(7.5×5.2)+(5.2×3)+(3×7.5)}cm

2(39+15.6+22.5)cm

2(77.1)cm

=154.2cm^2
