Lp = ( 2 x p x l ) + ( 2 x p x t ) + ( 2 x l x t ) 352 = ( 2 x 3a x 2a ) + ( 2 x 3a x a ) + ( 2 x 2a x a ) 352 = 12a^2 + 6a^2 + 4a^2 352 = 22a^2 a^2 = 16 a = 4
a) Masukkan nilai a nya p = 3a = 3(4) = 12 cm l = 2a = 2(4) = 8 cm t = a = 4
b) V = p x l x t = 12 cm x 8 cm x 4 cm = 384 cm^3

Anggapan: panjang 3x lebar 2x tinggi x 352=2(pxl)+2(pxt)+2(lxt) 176=pxl + pxt + lxt 176= 6x^2 + 3x^2 + 2x^2 176= 11x^2 x^2 = 16 x=4 maka a)panjang 12 cm, lebar 8cm, tinggi 4cm b)V=pxlxt = 12.8.4 = 384 cm^3
352 = ( 2 x 3a x 2a ) + ( 2 x 3a x a ) + ( 2 x 2a x a )
352 = 12a^2 + 6a^2 + 4a^2
352 = 22a^2
a^2 = 16
a = 4
a) Masukkan nilai a nya
p = 3a = 3(4) = 12 cm
l = 2a = 2(4) = 8 cm
t = a = 4
b) V = p x l x t = 12 cm x 8 cm x 4 cm = 384 cm^3
panjang 3x
lebar 2x
tinggi x
352=2(pxl)+2(pxt)+2(lxt)
176=pxl + pxt + lxt
176= 6x^2 + 3x^2 + 2x^2
176= 11x^2
x^2 = 16
x=4
maka a)panjang 12 cm, lebar 8cm, tinggi 4cm
b)V=pxlxt = 12.8.4 = 384 cm^3
