To find the total mass of an average man's brain and heart, we can use the following known average masses:

1. The average mass of an adult man's brain is approximately 1.4 kg.
2. The average mass of an adult man's heart is approximately 0.3 kg.

Now, we can calculate the total mass by adding these two values together:

$$
\text{Total mass} = \text{Mass of brain} + \text{Mass of heart}
$$

Substituting the known values:

$$
\text{Total mass} = 1.4 \, \text{kg} + 0.3 \, \text{kg}
$$

Now, let's perform the calculation:

$$
\text{Total mass} = 1.4 + 0.3 = 1.7 \, \text{kg}
$$

Thus, the total mass of an average man's brain and heart is **1.7 kg**.
The total mass of an average man's brain and heart is 1.7 kg.
