tolong jawab ya tolong.... bsk dikumpulin

A. V = La × T

= (1/2 × A × T) × T

= (1/2 × 28 × 21) × 32

= (1 × 14 × 21) × 32

= 294 × 32

= 9.408 cm^3


B. V = La × T

= (1/2 × A × T) × T

= (1/2 × 48 × 25) × 50

= (1 × 24 × 25) × 50

= 600 × 50

= 30.000 cm^3


C. V = La × T

= (1/2 × A × T) × T

= (1/2 × 32 × 28) × 46

= (1 × 16 × 28) × 46

= 448 × 46

= 20.608 cm^3


D. V = La × T

= (1/2 × A × T) × T

= (1/2 × 32 × 24) × 35

= (1 × 16 × 24) × 35

= 384 × 35

= 13.440 cm^3
