Doubling all the dimensions of a triangular pyramid, the volume of the pyramid becomes quadrupled.

Explanation:

The volume of the triangular pyramid is given by

$V_{1}=\frac{1}{3} \cdot b \cdot h$

where b is the base of the pyramid and

h is the height of the pyramid.

Doubling all the dimensions of the pyramid, we have,

b=2b and h=2h

Thus, volume of the triangular pyramid is given by

$V_{2}=\frac{1}{3} \cdot2b \cdot 2h$

Multiplying, we get,

$V_{2}=\frac{1}{3}4bh

$V_{2}=4\frac{1}{3}bh

V_2$=4 \cdot V_{1}$

Thus, doubling all the dimensions of a triangular pyramid, the volume of the pyramid becomes quadrupled.

leonid [27]

First, calculate 40% of 90

90 x (40/100 ) = 90 x 0.4 = 36

A. 72 NO

B. 36 YES

C. 4/5 x 9 = 36/5 NO

D. 40/100 / 90 = 1/225 NO

E. 2/5 x 90 = 36 YES

If it's 10

There are 6 time zones in the US: Hawaiian, Alaskan, Pacific, Mountain, Central, and Eastern. To figure out the time in different zones start with what you know: It's 10 am in the Eastern zone, and LA is in Pacific time. Now go back to the list and count backwards from Eastern to Pacific: 3. For each different time zone subtract 1 from 10: 10-3=7. In LA it would be C. 7 am :)
