5dregensleyerjawaban soal A Krangka = 4 ( p + l + t ) = 4 ( x + 6 + x + x - 5) = 4 ( 3x + 1) = 12x + 4 jawaban soal B krangka = 100 12x + 4 = 100 12x = 100 - 4 12x = 96 x = 96/12 x = 8 panjang = x + 6 = 8 + 6 = 14 lebar = x = 8 tinggi = x - 5 = 8-5 = 3 jawaban soal C VOLUM = p x l x t = 14 x 8 x 3 = 336 cm³
Krangka = 4 ( p + l + t )
= 4 ( x + 6 + x + x - 5)
= 4 ( 3x + 1)
= 12x + 4
jawaban soal B
krangka = 100
12x + 4 = 100
12x = 100 - 4
12x = 96
x = 96/12
x = 8
panjang = x + 6
= 8 + 6
= 14
lebar = x
= 8
tinggi = x - 5
= 8-5
= 3
jawaban soal C
VOLUM = p x l x t
= 14 x 8 x 3
= 336 cm³
