How many significant figures are in 0.04450 m? A 6 B 4 C 5 D 3 Question 2 Find the density, ing/cm3, of ametal cubewith a mass of 50.3 g andan edgelength (I) of 2.65 cm. For acube, V=13. A 6.33g/cm3 B 2.70g/cm3 C 19.0g/cm3 D 0.0222g/cm3

**Question 1:**The correct answer is **B 4**.* Leading zeros (the zeros before the first non-zero digit) are not significant. In 0.04450, the two zeros before the '4' are not significant.* Trailing zeros (zeros after the last non-zero digit) in a number with a decimal point are significant. The zero after the '5' is significant.* All non-zero digits are significant. The '4', '4', and '5' are significant.Therefore, there are four significant figures.**Question 2:**The correct answer is **B **.Here's the solution:1. **Calculate the volume (V) of the cube:** V = l³ = (2.65 cm)³ = 18.61 cm³2. **Calculate the density (ρ):** ρ = mass / volume = 50.3 g / 18.61 cm³ = 2.70 g/cm³ (rounded to three significant figures, as justified by the given data)
