tolong dikumpulin besok

dik:lpb=4.552 cm²
p=32 cm
l=28 cm
dit: t=....???
jwb:
lpb=2pl+2pt+2lt
4.552=2(32)(28)+2(32)(t)+2(28)(t)
4.552=1.792+64t+56t
4.552–1.792=120t
2760=120t
t=23 cm

semoga membantu.....

penyelesaian :
Dik :
v = 4.552 cm²
p = 32 cm
L = 28 cm
Dit : t?

jawab :
v = p x l x t
4.552 = 32 x 28 x t
t = 4.552/ 32 x 28
t = 4.552 / 896
t = 5 ,02 cm
