Step 2

Ans 1 - A 1145 g block of wood has the measurement of 11.2 cm ×12.1 cm×13.6 cm.

Therefore,

Mass of wood = 1145 g

Volume of wood = Volume of cuboid = l×b×h

Mass of metal Density of metal Volume occupied by the metal Volume occupied by the metal in graduated cylinder = 34.8 mL - 22.6 mL= 12.2 mL As we know that, 1 ml = 1 cm2, thus Volume occupied by the metal in cylinder = 12.2 cm Density of metal- 08.948 g = 8.93 g/em 122 am Hence, the metal is copper.
