Copper plate

Calculate the thickness of the copper plate with a density 8.7 g/cm³ measuring 1.5 meters and 80 cm and its weight is 3.65 kg

Result

h =  0.035 mm

Solution:

m=3.65⋅ 1000=3650 r=8.7 S=150⋅ 80=12000 V=m/r=3650/8.7≐3650087≐419.5402 h=V/S=419.5402/12000≐732088≐0.035≐0.035 mmm=3.65 \cdot \ 1000=3650 \ \\ r=8.7 \ \\ S=150 \cdot \ 80=12000 \ \\ V=m/r=3650/8.7 \doteq \dfrac{ 36500 }{ 87 } \doteq 419.5402 \ \\ h=V/S=419.5402/12000 \doteq \dfrac{ 73 }{ 2088 } \doteq 0.035 \doteq 0.035 \ \text{mm}
