Question

A water tank is 10m long and 8m wide if the depth of the tank is 5m find the volume of the water in the tank? ​

Answer 1

Answer:

The tank is a cuboid open at the top.

Surface area of a cuboid = 2(LB +BH + hl)

Surface area of a tank open at top = Surface area of cuboid - Area of the portion open at the top i.e.

2(LB + BH + hl) - LB = 2 (10*5 + 5*3 + 3*10) - 10*5

2(50+15+30) - 50 = 2*95 - 50 = 190 -50 = 140m sq.

Step-by-step explanation:

Answer 2

Answer:

Since Length, Breadth and Height is given. It is understood that the water tank is a cuboid.

Length=10m

Breadth=8m

Depth=Height=5m

So, Volume of the water in the tank=Volume of Cuboid

                                                          =lbh

                                                          =10x8x5=400sq.m
