Question: 1 / 400

What is the total weight of a standard steel plate measuring 4' wide, 8' long, and 1" thick, given that steel weighs 490 lbs/ft3?

1,206.6 lbs

1,306.6 lbs

To determine the total weight of a standard steel plate, we need to calculate the volume of the steel plate first, and then multiply that by the weight of steel per cubic foot.

1. **Calculate the volume of the steel plate**:

The dimensions of the plate are as follows:

- Width: 4 feet

- Length: 8 feet

- Thickness: 1 inch. To convert the thickness from inches to feet, we divide by 12. Thus, 1 inch equals \( \frac{1}{12} \) feet.

Now we can calculate the volume in cubic feet:

\[

\text{Volume} = \text{Width} \times \text{Length} \times \text{Thickness}

\]

\[

\text{Volume} = 4 \, \text{ft} \times 8 \, \text{ft} \times \frac{1}{12} \, \text{ft} = \frac{32}{12} \, \text{ft}^3 = \frac{8}{3} \, \text{ft}^3 \approx 2.6667 \, \
