Work out the surface area of the solid cuboid.

If ℓ, b and h denote respectively the length, breadth and height of a cuboid, then Total surface area of the cuboid = 2 (ℓb + bh + ℓh) square units. Volume of the cuboid = Area of the base × height = ℓ × b × h cubic units. where base area = Breadth × length

Hopefully, this helps! :D

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

it's the only multiple of both and the least
