A commonly used unit of mass in the English system is the pound-mass, abbreviated lbm, where 1 lbm = 0.454 kg. What is the density of water in pound-mass per cubic foot?

What is the total surface area of a right circular cylinder with a radius of 2.3 cm and a height of 1.4 cm?

A spherical tank is full of water with total mass 10,000kg. If outside diameter is 2772 mm, the thickness of the tank wall is______mm?

What is the area of a circle of radius (a) 11.37 m and (b) 6.8 m?

Estimate the volume of the earth in m3 by assuming that its radius is 6400 km.

In the Bible, Noah is instructed to build an ark 300 cubits long, 50 cubits wide and 30 cubits high. (A cubit was a unit of length based on the length of the forearm and equal to half of a yard.) What would the dimensions of the ark be in meters? What would its volume be in cubic meters? (Assume that the ark was rectangular.)

The area of a triangle is given by the formula  A = 1/2 bh,  where A is the area, b is the length of the base, and h is the triangle's height. If a triangle has a base 6 meters long and a height twice the length of the base, find its area. Because b is given to be _______ meters long, substitute _____  for b in the given formula for the area of a triangle. A=1/2bh A=1/2 ( ? )h
