Question

Sebuah balok dengan p : l : t = 4 : 3 : 1. jika luas permukaannya 950 cm³.
hitung :
a.) p,l,t
b.) volumenya

Answer 1

Lp = 2(pl+pt+lt)
950= 2([email protected]@[email protected]@[email protected]@)
950x2=([email protected]^[email protected]^[email protected]^2)
1900 =([email protected]^2)
@^2 =1900/19=100
@ =√100
@ =10 cm (@ sbg variabel pngganti)

a. p= [email protected]=4x10=40cm
l = [email protected]= 3x10=30cm
t = [email protected]= 1x10 =10cm

b. volume = pxlxt
volume = 40x30x10 = 12000 cm^3
