Answer:
<h3>Density = 0.5 g/cm³</h3>Explanation:
Density of a substance can be found by using the formula
From the question
mass = 32g
To find the density we must first find the volume of the block
From the question the block is a cuboid
Volume of cuboid = length × width × height
length = 8 cm
width = 4 cm
height = 2 cm
Volume of block = 8 × 4 × 2 = 64 cm³
Substitute the values into the above formula and solve for the density
That's....
We have the final answer as
Density = 0.5 g/cm³
The block will float because it's density is less than the density of water which is
1 g/cm³
