The given expression is:

\[
(5.36 \times 10^{-4})^3 + (3.13 \times 10^{-5}) \times (2.48 \times 10^{-6})
\]

We need to calculate this expression using a calculator and give the answer in standard form to **3 significant figures**.

### Step 1: Calculate \((5.36 \times 10^{-4})^3\)
\[
(5.36 \times 10^{-4})^3 = 5.36^3 \times (10^{-4})^3 = 153.94 \times 10^{-12} = 1.5394 \times 10^{-10}
\]
(rounded to 5 decimal places for intermediate steps)

### Step 2: Calculate \((3.13 \times 10^{-5}) \times (2.48 \times 10^{-6})\)
\[
(3.13 \times 10^{-5}) \times (2.48 \times 10^{-6}) = 3.13 \times 2.48 \times 10^{-5 - 6} = 7.7624 \times 10^{-11}
\]

### Step 3: Add the two results
Now, add the two values calculated:

\[
1.5394 \times 10^{-10} + 7.7624 \times 10^{-11} = (1.5394 + 0.77624) \times 10^{-10} = 2.31564 \times 10^{-10}
\]

### Step 4: Round the result to 3 significant figures
The result to 3 significant figures is:

\[
2.32 \times 10^{-10}
\]

Thus, the final answer is **\( 2.32 \times 10^{-10} \)**.
