Find the volume of this figure

1920 cm³

Step-by-step explanation:

For the left figure:

10 • 8 • 14 =

80 • 14 = 1120

For the right figure:

10 • 10 • 8 =

100 • 8 = 800

Add together : 1120 + 800 = 1920 cm³

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

think about it deeply and passionately about this property

i am sorry
