What the volume of the figure

1530 cm^3

Step-by-step explanation:

They are two Rectangular Prism.

prism 1.

lengthl = 18 cm

widthw = 10 cm

heighth = 4 cm

diagonald = 20.976177 cm

total surface areaS_tot = 584 cm^2

lateral surface areaS_lat = 224 cm^2

top surface areaSt_op = 180 cm2

bottom surface areaS_bot = 180 cm^2

volumeV = 720 cm^3

Prism 2.

lengthl = 10 cm

widthw = 9 cm

heighth = 9 cm

diagonald = 16.1864141 cm

total surface areaS_tot = 522 cm^2

lateral surface areaS_lat = 342 cm^2

top surface areaStop = 90 cm^2

bottom surface areaSbot = 90 cm^2

volumeV = 810 cm^3

Add 720 cm^3+810 cm^3 = 1530 cm^3

Agenda: l = length

w = width

h = height

d = diagonal

S_tot = total surface area

S_lat = lateral surface area

S_top = top surface area

S_bot = bottom surface area

V = volume

Formula: Volume of Rectangular Prism:  V = lwh

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
