<u>Answer:</u>
density of solid = 4.5 g/cm³
<u>Explanation:</u>
density = mass ÷ volume
• We know the mass of the object (135 g). We need to calculate the volume:
Volume = length × width × thickness
= 5 cm × 3 cm × 2 cm
= 30 cm³
• Now we can calculate the solid's density:
density = 135 g ÷ 30 cm³
= 4.5 g/cm³
