Question

The length of a cuboid is thrice its breadth
and the height is
5cm. Find the total surface
area of the cuboid if its volume is
1500m³​

Answer 1

Step-by-step explanation:

volume = l*b*h

1500= 3b*b*5

300= 3b^2

b^2 = 100

b= 10

so L = 3b

3*10

= 30

total surface area = 2(lb+bh+hl)

= 2(30*10+10*5+5*30)

= 2(300+50+150)

= 2(500)

= 1000

Answer 2

Answer:

Given Length of cuboid=10cm

Breadth of cuboid =5cm

Height of cuboid=3cm

∴ Volume of a cuboid=Length×breadth×height

                                    =10×5×3

                                    =150cm
