The volume of an oblique pyramid with a square base is v units3 and the height is h units.

an oblique pyramid with a square base has a volume of v units cubed and a height of h units.

which expression represents the area of the base of the pyramid?

startfraction 3 v over h endfraction units2
(3v – h) units2
(v – 3h) units2
startfraction v over 3 h endfraction units2

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec.
