Answer:
1530 cm^3
Explanation:
They are two Rectangular Prism.
prism 1.
length l = 18 cm
width w = 10 cm
height h = 4 cm
diagonal d = 20.976177 cm
total surface area S_tot = 584 cm^2
lateral surface area S_lat = 224 cm^2
top surface area St_op = 180 cm2
bottom surface area S_bot = 180 cm^2
volume V = 720 cm^3
Prism 2.
length l = 10 cm
width w = 9 cm
height h = 9 cm
diagonal d = 16.1864141 cm
total surface area S_tot = 522 cm^2
lateral surface area S_lat = 342 cm^2
top surface area Stop = 90 cm^2
bottom surface area Sbot = 90 cm^2
volume V = 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
