Check the picture.
The bases of the 2 prisms are on 2 parallel planes,
a and
b.
Let
c be a third plane, between
a and
b, parallel to both.
Then,
the cross-sections
A and
B , of the 2 prisms, formed by plane c, have
Equal Areas,
this is by
Cavalier's Principle.
Answer:
A. 8100
Step-by-step explanation:
85 x 86
To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.
85*100 = 8500
Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.
