A tank measures 20m in length, 5m in breadth and it is 25m tall what is the total surface area of thetank

Step-by-step explanation:

Surface area of the tank is

2( lb + bh + lh)

Where l is the length

b is the breath

h is the height

From the question

l = 20m

b = 5m

h = 25

Surface area of the tank is

2 ( 20 × 5 + 5 × 25 + 20 × 25)

2 ( 100 + 125 + 500)

2 ( 725)

The final answer is

Hope this helps you.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
