Question

A bar of gold measures 0.14 m times 0.053 m times 0.044 m. How many gallons of water have the same mass as this bar? gal Interactive Solution 11.13 offers help in modeling this problem. A solid concrete block weighs 174 N and is resting on the ground. Its dimensions are 0.400 m times 0.200 m times 0.100 m. A number of identical blocks are then stacked on top of this one. What is the smallest number of whole blocks (including the one on the ground) that can be stacked so that their weight creates a pressure of at least two atmospheres on the ground beneath the first block? bricks

Explanation / Answer

V = 0.14*0.053*0.044 = 3.26*10^-4
Mass= rho*V = 19300*V = 6.301064 kg
Volume of this mass of water = 6.301064 litres = 1.6645649139 gallons

W = 174 N
V = 3.26*10^-4 m^3
P = 2*1.01*10^5 pa = n*174/0.4*0.2
n = 93 blocks
