Answer:
(A) 24 [tex]mm^{3}[/tex]
Step-by-step explanation:
Length of the first piece = 8 - 6 = 2 mm
Width of the first piece = 1 mm
Height of the first piece = 6 mm
Volume of the first piece = 2 × 1 × 6= 12[tex]mm^{3}[/tex]
Length of the second piece = 6 mm
Width of the second piece = 1 mm
Height of the second piece = 6 - 4 = 2 mm
Volume of the first piece = 6 × 1 × 2= 12[tex]mm^{3}[/tex]
Volume of the entire solid = 12 + 12 = 24 [tex]mm^{3}[/tex]
