Use our Rectangular Solid Calculator to quickly determine the volume and surface area of any rectangular prism. Enter the length, width, and height, select your units, and get instant, accurate results for your geometry problems, construction projects, or educational needs.
Formula:
The Rectangular Solid Calculator computes both volume and surface area based on three dimensions:
Volume (V) = length (L) × width (W) × height (H)
Formula: V = LWH
Surface Area (SA) = 2 × (length (L) × width (W) + length (L) × height (H) + width (W) × height (H))
Formula: SA = 2(LW + LH + WH)
