Jawab: Yang Ke 1 ( Kubus ) = LP Kubus = 6 x s² = 6 x 12 x 12 = 864 Cm² V Kubus = s³ = 12x12x12 = 1728 Cm³
Yang Ke 2 ( Persegi Panjang ) = LP Persegi Panjang = 2 x [ P x L ] + [ P x T ] + [ L × T ] = 2 X [ 35 X 25 ] + [ 35 X 15 ] + [ 25 X 15 ] = 2 X [ 875 ] + [ 525 ] + [ 375 ] = 2 x 1775 = 3550 Cm²
V Persegi Panjang = p x l x t = 35 x 25 x 15 = 13.125 Cm³
Yang Ke 3 ( Limas ) =
LP Limas = L. Alas x LSST = ( 40 X 40 ) + ( 4 x 1/2 x 40 x 15 ) = ( 1.600 ) + ( 4 X 300 ) = 1.600 + 1200 = 2.800 Cm²
V Limas = 1/3 X luas Alas X Tinggi Limas = 1/3 X ( 40 X 40 ) X 16 Cm = 1/3 X 1600 X 16 Cm = 25.600 ÷ 3 = 8.533 Cm³
