Answer:
14 ft³
Step-by-step explanation:
Previous wardrobe : 7 feet tall, 3 feet wide, and 2 feet long
Volume of previous wardrobe = length × width × height
= 7 ft × 3 ft × 2 ft
= 42 ft³
Volume of previous wardrobe = 42 ft³
New wardrobe: 7 feet tall, 4 feet wide, and 2 feet long
Volume of new wardrobe = length × width × height
= 7 ft × 4 ft × 2 ft
= 56 ft³
Volume of new wardrobe = 56 ft³
What is the difference in volume of the two wardrobes?
Difference in volume of new wardrobe and previous wardrobe = Volume of new wardrobe - Volume of previous wardrobe
= 56 ft³ - 42 ft³
= 14 ft³
Difference in volume of new wardrobe and previous wardrobe = 14 ft³
