This is a rectangular prism. Its volume is V = (length)(width)(height).
Here, V = (10 cm)(3 cm)(2 cm) = 60 cm^3.
Yes. A trapezoid is defined as a <span>quadrilateral with two sides parallel, so a trapezoid with three right angles is just a square!</span>
(1) R+G+B=50
(2) R=B+6
(3) G=B-4 so substitute G in (1)
R+B-4+B=50 substitute (2) in here
B+6+B-4+B=50 group like terms and solve
3B+2=50
3B=50-2
B=48/3=16 substitute in (2) and (3)
R=16+6=22
G=16-4=12
Check
22+12+16=50✅
