Answer:
V = 5 cm³
ρ = 4 g/cm³
Explanation:
Step 1: Calculate the volume (V)
We have a wooden cuboid of dimensions 5 cm × 1 cm × 1 cm. We can calculate its volume using the following expression.
V = 5 cm × 1 cm × 1 cm
V = 5 cm³
Step 2: Calculate the density (ρ)
The density is equal to the mass divided by the volume.
ρ = m / V
ρ = 20 g / 5 cm³
ρ = 4 g/cm³

1) The type of bond in metalloids to metal is metallic bond.
Metallic bond is a type of chemical bond.
Metallic bond is formed between electrons and positively charged metal ions.
Metallic radius is defined as one-half of the distance between the two adjacent metal ions.
Metallic bond increace electrical and thermal conductivity.
Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.
2) The type of bond in nonmetal is covalent bond.
Nonmetals have low electrical and thermal conductivity.
