Answer:

1240 in³

Step-by-step explanation:

The overall dimensions of the block are ...

10 in by 11 in by 17 in

The volume of that space is ...

V = LWH = (10 in)(11 in)(17 in) = 1870 in³

The volume of each of the three identical holes is similarly found:

V = (10 in)(3 in)(7 in) = 210 in³

Then the volume of the block is the overall volume less the volume of the three holes:

= 1870 in³ - 3(210 in³) = 1240 in³
