Answer:
Total volume = 355 cm³
Step-by-step explanation:
Volume of the irregular prism = volume of part A + volume of part B
Volume of part A which is also a rectangular prism = Length × width × height
= (11 - 5) × 5 × 6
= 6 × 5 × 6
= 180 cm³
Volume of rectangular prism B = 5 × 5 × (6 + 5)
= 5 × 5 × 11
= 275 cm³
Total volume = 180 + 175
= 355 cm³
