(A) 3.5 m
(B) 4.1 m
(C) 5.2 m
(D) 6.6 m
🧠 Explanation:
Step 1 – Find the tank’s total volume in cubic meters**
Length × Width × Height = $4 \times 2 \times 4.8 = 38.4\ \text{m}^3$.
**Step 2 – Water initially in the tank**
Three-quarters full means:
$\frac{3}{4} \times 38.4 = 28.8\ \text{m}^3$.
**Step 3 – Add the new water volume**
4000 liters = 4 cubic meters (since 1000 L = 1 m³).
So: $28.8 + 4 = 32.8\ \text{m}^3$ of water in total.
**Step 4 – Find the new depth**
The base area of the tank is $4 \times 2 = 8\ \text{m}^2$.
Depth = $\frac{\text{Volume}}{\text{Base area}} = \frac{32.8}{8} = 4.1\ \text{m}$.
So, what depth do you get for the water now? Looks like it’s **4.1 m** — do you want me to also explain how it compares to the tank’s total height?
