This is an expanded view of a cuboid carton. What is the volume of the carton?
14 × 12 × 5 = 168 × 5 = 840 (CC). A: the volume of this carton is 840 CC
The following is an expanded view of six sides of a cuboid. Find the surface area and volume of the cuboid. (unit: cm)
S=(10×5+10×15+5×15）×2=550（cm²）
V=5×10×15=750（cm³）
The picture is a bit lazy & don't mind
The total edge length of a cuboid is 24cm, and the ratio of its length, width and height is 5:4:3. What is the surface area and volume of the cuboid?
5 + 4 + 3 = 1224 △ 4 = 6 (CM) 6 × 512 = 2.5 (CM) 6 × 412 = 2 (CM) 6 × 312 = 1.5 (CM) surface area: (2.5 × 2 + 2.5 × 1.5 + 2 × 1.5) × 2 = (5 + 3.75 + 3) × 2 = 11.75 × 2 = 23.5 (cm2) volume: 2.5 × 2 × 1.5 = 7.5 (CC). Answer: the surface area of this cuboid is 23.5 square cm, and the volume is 7.5 cubic cm
The figure below is an expanded view of the cuboid. The relevant data have been given to calculate the surface area and volume of the cuboid
Cuboid surface area: (8 × 5 + 5 × 3 + 3 × 8) × 2, = (40 + 15 + 24) × 2, = 79 × 2, = 158 (square decimeter); cuboid volume: 8 × 5 × 3, = 40 × 3, = 120 (cubic decimeter); answer: the cuboid surface area is 158 square decimeter, the volume is 120 cubic decimeter
