Lp balok =2×(p×l)+(p×t)+(l×t)
v balok= p×l×t
soal
5. lp= 2×(18×8)+(18×12)+(8×12)
= 2×(144+216+96)
= 2×456
= 912 cm²
v =18×8×12
=1.728 cm³
6. lp= 2×(22×14)+(22×18)+(14×18)
= 2×(308+396+252)
= 2×956
= 1.912 dm²
v=22×14×18
=5.544 dm³
7. lp= 2×(22×13)+(22×16)+(13×16)
= 2×(286+352+208)
= 2×846
= 1.692 cm²
V=22×13×16
=4.576 cm³
8. lp= 2×(22×10)+(22×14)+(10×14)
= 2×(220+308+140)
= 2×668
= 1.336 dm²
v=22×10×14
=3.080 dm³
Jawab:
5. V = 1.728 cm^3
L = 456 cm^2
6. V = 5.544 dm^3
L = 1.912 dm^2
7. V = 4.576 cm^3
L = 1.666 cm^2
5. V = p x l x t = 18 cm x 8 cm x 12 cm = 1.728 cm^3
L = 2 x ( pl + pt + lt ) = 2 x ( 18 cm x 8 cm + 18 cm x 12 cm + 8 cm x 12 cm )
= 2 x ( 144 cm + 216 cm + 96 cm ) = 456 cm^2
6. V = p x l x t = 22 dm x 14 dm x 18 dm = 5.544 dm^3
L = 2 x ( pl + pt + lt ) = 2 x ( 22 dm x 14 dm + 22 dm x 18 dm+14dmx18dm)
= 2 x ( 308 dm + 396 dm + 252 dm ) = 2 x 956 dm = 1.912 dm^2
7. V = p x l x t = 22 cm x 13 cm x 16 cm = 4.576 cm^3
L = 2 x ( pl + pt + lt ) = 2 x ( 22 cm x 13 cm + 22 cm x 16 cm + 13 cm x 16cm )
= 2 x ( 286 cm + 352 cm x 195 cm ) = 2 x 833 cm = 1.666 cm^2
8. V = p x l x t = 22 dm x 10 dm x 14 dm = 3.080 dm^3
L = 2 x ( pl + pt + lt ) = 2 x ( 22 dm x 10 dm + 22 dm x 14 dm + 10 dm x 14 dm )
= 2 x ( 220 dm + 308 dm + 140 dm ) = 2 x 668 dm^2 = 1.336 dm^2
Semoga bermanfaat :)
