<em><u>Solution:</u></em>
<em><u>The surface area of cube is given as:</u></em>
Where,
"s" is the length of each side of cube
From given,
s = 5.2 inches
Therefore,
Thus the surface area of cube is 162.24 square inches
Answer:
divide the previous value by 5
Step-by-step explanation:
5^2=25, 5^1=5, 25/5=5
Answer:
Kenny is 18 years old Andrew is 10 years old Tim is 30 years old and Cameron is 5 years old
Step-by-step explanation:
Let a be Kenny's age , b be Andrew's age , c be Tim's age , d be Cameron's age
( b < a , b<c , d<b)
Kenny is 8 years older than Andrewn = > a = b + 8 (1)
Tim is 3 times as old as Andrew => c = 3 . b (2)
Cameron is 5 years younger than Andrew => d = b-5 (3)
The combined age of the four is 63 => a+b+c+d = 63 (4)
(1),(2),(3),(4) => b+8 + b + 3b + b-5 = 63 <=> 6b + 3 = 63 <=> b = 10
=> a= 10+8 =18, c = 3 . 10 = 30, d= 5
