Question

tolong di jawab pakai cara yg bnr makasih ​

Answer 1

a. V.kubus= S×S×S

= 10×10×10

= 1.000Cm

V.Balok= P×L×T

= 20×10×12

=2.400Cm

Volume gabungan = 3.400cm

b. V.tabung =1/2×π×r²×t

=1/2×22/7×7×7×20

=1/2×22×7×20

=1/2×154×20

=1/2×3.080

=1.540Cm

V.Balok= P×L×T

=20×14×8

=280×8

=2.240

Volume gabungan= 1.540+2.240=3.780
