Using the distributive property of multiplication over addition, x*[x - x] = x*[x + (-x)] = x*x + x*(-x)LHS = x*0 = 0RHS = x^2 + x*(-x)Therefore x*(-x) = -x^2 and, by commutativity, -x*x = -x^2Next-x*[x - x] = -x*[x + (-x)] = -x*x + -x*(-x)LHS = -x*0 = 0RHS = -x^2 + -x*(-x)Therefore (RHS) -x times -x = +x^2 (LHS).

210mm x 297mm = 62,370 mm62,370mm / (304.8mm/foot) = 204.6 feetOne foot contains 304.8mm.
210 x 297 millimetres = 8.26771654 x 11.6929134 inches
The A refers to the international standard paper size ISO216 series A4 size of 210mm x 297mm.
210mm & 297mm sides
As specified by the International Organization for Standardization (ISO), based in Geneva, Switzerland, the size dimensions of A3 paper are 297 by 420 millimeters (11.69 by 16.54 inches).
If you're talking about the dimensions of an A4 sheet of paper. In metric it's 210mm x 297mm. In imperial it's approximately 8.27 x 11.69 inches.
The A4 paper size is defined as 210mm x 297mm because it is based on the international standard ISO 216, which uses a 1:√2 aspect ratio. This ratio ensures that when you fold the paper in half, the resulting dimensions maintain the same aspect ratio. This standardized size makes it easier to scale and reproduce documents consistently across different devices and countries.
The basis used by the International Standard ISO 216 is the German DIN 476 which is known in all European countries as A4. One can find the dimensions for A4 paper in Wikipedia which is: Width 210mm x Height 297mm.
A5 = 148 x 210mm A4 = 210 x 297mm A3 = 297 x 420mm A2 = 420 x 594mm A1 = 594 x 841mm A0 = 841 x 1189mm 2A0 = 1189 x 1682mm 4A0 = 1682 x 2378mm
A4 is 210mm × 297mm = 62,370 square millimetres 26cm x 32cm x 10cm = 8,320 square centimetres (83,200 square millimetres) Therefore Yes, 26 x 32 x 10 cm is bigger than A4
