Answer:
72. If the second 3cm has some relevance, leave a note and I'll come back and modify my answer.
Step-by-step explanation:
Givens
L = 6 cm
W = 3 cm
H = 2 cm
I don't know what the extra 3 cm is for.
Formula
SA = 2*L*W + 2*L*H + 2*H*W
SA = 2*6*3 + 2*6*2 + 2*2*3
SA = 36 + 24 + 12
SA = 72
She will have 6 braces left over since 8x8=64 and 70-64=6
Answer: 3
Step-by-step explanation:
Given :
343
We need to write 343 in index form of 7.
343 is the same as
, replacing 343 with
, we have

Recall one on the law of Logarithm :

can be written as c
b
So,
can be written as ;
3
7
Also from the laws of Logarithms ,
a = 1
so , Log_{7}[/tex] 7 = 1
The solution then becomes
3 x 1 = 3
Therefore :
343 = 3
