Total Surface Area (TSA): \(2(lb + bh + hl)\) — the total area of all 6 faces. Lateral Surface Area (LSA): \(2h(l + b)\) — the area of the 4 side walls (excluding top and bottom). Volume: \(l \times b \times h\) — the total space inside the cuboid. Diagonal: \(\sqrt{l^{2}+b^{2}+h^{2}}\) — the longest straight line inside the cuboid. The surface area and volume of a cuboid and a cube are calculated using basic geometric formulas based on their length, width (breadth), and height.
