luas bangun t 25 l 20cm dan alas 30 cm

A x L x T = 30 x 20 x 25 = 15.000

Lp = 2 × ( (a × l) + (l × t) + (a × t) )

a = 30 cm
l = 20 cm
t = 25 cm

Lp = 2 ( (30 × 20) + (20 × 25) + (30 × 25) )
= 2 ( (600) + (500) + (750)
= 2 ( 600 + 500 + 750 )
= 2 ( 1.100 + 750 )
= 2 × 1.850
= 3.700 cm^2

V = a × l × t
= 30 cm × 20 cm × 25 cm
= 600 cm^2 × 25
= 15.000 cm^3

Semoga bermanfaat \^_^/
