1. What is Volume and Area of 3D Shapes Calculator?

Definition: This calculator computes the volume and surface area of various 3D shapes including rectangular prisms and cylinders.

Purpose: It helps in construction, engineering, and design projects where accurate volume and surface area calculations are needed for material estimation and planning.

2. How Does the Calculator Work?

The calculator uses different formulas based on the selected shape:

Rectangular: \( V = L \times W \times H \)

Surface Area: \( SA = 2(LW + LH + WH) \)

Cylindrical: \( V = \pi \times r^2 \times h \)

Surface Area: \( SA = 2\pi r(r + h) \)

Where:

\( V \) — Volume (cubic units)
\( SA \) — Surface Area (square units)
\( L \) — Length (units)
\( W \) — Width (units)
\( H \) — Height (units)
\( r \) — Radius (units)
\( h \) — Height (units)

3. Importance of Volume and Area Calculations

Details: Accurate volume calculations are essential for material estimation, while surface area is crucial for painting, coating, or wrapping applications.

4. Using the Calculator

Tips: Select the shape, enter the required dimensions, and click Calculate. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: You can use any consistent unit (meters, feet, inches, etc.), just ensure all dimensions use the same unit.
