Step-by-step explanation:
Given:
Length of a cube is 2 cm
To Find:
Surface area of the cube
Solution:
A cube consists of 6 faces.
The area of each face = side x side
So, the total surface area of a cube = 6 x
side x side
Let a be the length of the given cube
: Surface area of a cube = 6a square
a = 2 cm (Given)
Surface area of cube = 6 x 22 =(6 x 4) = 24 cm square.
Hence, the surface area of the given
cube is 24cm square.
Hope it helps!
For number 9 you have to convert from fraction to precent, the way i do this is by multiplying my denominator by a variable to get 100.
in this instance my denominator is 5 so 5x=100 in this case we are multiplying by 20. so 1(20)=20. it is important to recognize that 1/5 is equal to 20/100. now that we have an equivilent fraction we can use the numerator to be our precent. so the answer is A.20%
for number 10 we use the same idea. we know that 20 percent of people are for the visiting team so the rest of the pie chart would mean 80 percent of people were for the home team. We take the total number of people which is 64,000 and multiply our 80 percent, so we move the decimal
64,000(.80)=51200
so the answer for 10 is D.51200
Ur answer is A but am really beginning sure
