Answer 1

Figure 1

Answer: 350

Formula: W × H × L

7 × 5 × 10 = 350

Figure 2

Answer: 288

Formula:
`(1)/(2)bhl`

`(1)/(2)*8*6*12=288`

Figure 3

Answer: 14.7

Formula:
`(1)/(2) bhl`

`(1)/(2)*4.2*2*3.5=14.7`

Figure 4

Answer: 4.29

Formula: W × H × L

2.6 × 1.5 × 1.1 = 4.29

Figure 5

Answer: 60

Formula: W × H × L

4 × 3 × 5 = 60

Figure 6

Answer: 27.2

Formula:
`(1)/(2) bhl`

`(1)/(2)*4.1*2.6*5.1`

Figure 7

Answer:
`117(223)/(256)`

Formula: L × W × H

`8(7)/(8)*4(1)/(4)*3(1)/(8) =(30175)/(256)=117(223)/(256)`

Figure 8

Answer: 86.4

Formula:
`(1)/(2) bhl`

`(1)/(2)*6.1*4.8*5.9=86.4`
