You are given a cube of pure copper. You measure the sides of the cube to find the volume and weigh it to find its mass. When you calculate the density using your measurements, you get 8.78 grams/cm³. Copper’s accepted density is 8.96 g/cm³. What is your percent error?
5%
2%
3%
4%
What is the formula or equation used in calculating the volume of regular solids?
V= H x W x L
V= L x W x H
V= W x L x H
V= L x H x W
What is the formula or equation used in solving for the percent error?
% error = ( accepted value - measured value) x 100%
% error = ( accepted value - measured value) + 100%
% error = ( accepted value - measured value/ accepted value) x 100%
% error= ( error / measured value ) x 100%
