.What is the mass (in grams) of a copper block whose dimensions are 5 inch × 6 inch and whose density is 8.96 g/cc? (Given that 1 inch = 2.54 cm)

Question

.What is the mass (in grams) of a copper block whose dimensions are 5 inch × 6 inch and whose

density is 8.96 g/cc? (Given that 1 inch = 2.54 cm)

Answer 1

We need one more dimension to find the volume of this block, otherwise the answer cannot be found yet.

When we do find that last dimension, assuming it will be in inches like the other two dimensions, the formula will look like this:

X grams = (5 inch)(6 inch)(? Inch)[(2.54 cm/1 inch)^3](8.96 g/cc)
