What is the surface area of the cube below? 9 9 9
A. 508 units2
B. 405 units2
C. 486 units
D. 729 units2

The formula of the surface area of a cube is 6 x s²

→ s = 9  

→ s² = 9²  

→ s² = 81  

→ 6 x 81 = 486

So, the surface area of the cube is 486 units².

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
