Awaterbed filled with water has the dimensions 8.5ft by 7.5ft by 9.5inches. taking the density of water to be 1.00 g/cubic centimeter, determine the number of pounds of water required to fill the water bed.

First, 1 foot = 30.48cm (12 inches x 2.54 cm/inch=30.48 cm). So, 8,5 ft = 8.5 x 30.48cc=259.08 cm, 7.5 ft = 7.5 x 30.48=228.6cm and 9.5/12=0.791ft x 30.48 =24.11cm. So, in cc, 259.08 x 228.6 x 24.11 = 1,427,931.3 cc. Since 1 cc of water = 1 gram then we have 1,427,931`grams or 1427. 931 kg x 2.2 lbs/kg = 3141 pounds of water or 1.57 tonnes of water so with this size of waterbed if  upstairs the house structure must be able to withstand this stress. 

Ithink it’s one of those things that you put the object on

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
