Answer:
A = 20
Step-by-step explanation:
12/3 = A/5
60 = 3A
A = 60÷3 = 20
Circumfrence: pi times diameter
7.9*

circumfrence is approximatley 24.806
area:

a=

*(1/2(d))^2
a= 48.99
Answer:
960
Step-by-step explanation:
First of all we can find the volume of the whole box:
8×12×10=960
then find the area of the blocks:
1×1×1=1
Finally, we divide them to find how many fit in to the box:
960÷1=960
So 960 of the blocks will fit into the box.
<em>The answer is 25.12 exactly</em>
