Question

Panjang bak air 90 cm, lebar 70 cm, dan kedalamannya 60 cm. jikq tebal dinding bak 10 cm, maka volumenya ...L

Answer 1

V = (p x l x t) - ketebalan = (90 x 70 x 60)-10 = 3770

Answer 2

V=(pxlxt)
p=panjang bak - 2xtebal dinding=90-(10.2)=90-20=70
l=lebar bak - 2xtebal dinding=70-(10.2)=70-20=50
t=kedalaman bak - tebal dindinh=60-10=50
v=(pxlxt)
v=70x50x50=175000
