What is the surface area of the pyramid to the nearest whole number?

surface area of square pyramid = 132 square cm.

Step-by-step explanation:

Given : A pyramid of base square length =  6 cm  and slant height = 8 cm.

To find : What is the surface area of the pyramid to the nearest whole number.

Solution : We have given that

Square pyramid of base length =  6 cm  and slant height = 8 cm.

Formula for surface area of square pyramid =  b² + 2 * b *s

Where, b = base length  and s = slant height .

Plugging the values in formula : b = 6 cm , s = 8 cm.

Then ,  surface area of square pyramid = ( 6)² + 2 * 6 * 8.

surface area of square pyramid =  36 + 96.

surface area of square pyramid = 132 square cm.

Therefore,  surface area of square pyramid = 132 square cm.

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.
