<u>Answer:</u> The weight of water bed in pounds is 1850.16 lb
<u>Explanation:</u>
To calculate the volume of cuboid, we use the equation:
where,
V = volume of cuboid
l = length of cuboid = 210 cm
b = breadth of cuboid = 160 cm
h = height of cuboid = 25 cm
Putting values in above equation, we get:
(Conversion factor:
)
To calculate the mass of waterbed, we use the equation:
Density of waterbed =
Volume of waterbed =
Putting values in above equation, we get:
Hence, the weight of water bed in pounds is 1850.16 lb
