Jamesbond:

A wooden block of side of 4cm was cut into 8 smaller cubes of side of 2cm. If 1 litre of paint is required to paint the uncut wooden block, how many litres of paint is needed to paint the 8 smaller cubes?


Pl help...

area of uncut cube is 4*4*6=96cm2
area of eight cubes is 2*2*6*8=192cm2
192/96=2
96cm2 -------- 1liter
192cm2 needed 2 liters.

ans by ds

another way to solve is to count how many sides of 2cm x 2cm are there
uncut: 4 x 6 = 24
cut: 6 x 8 = 48
24 sides --> 1 L
48 sides --> 2 L

I dont know how to do it but I asked DD1 to try.


total sweets is 4u + 3 = 6u - 9
which is 2u = 12
a) so u = 6 grandchildren
b) 4u + 3 = 27 sweets

:thankyou:

2/5 of $480= $192 on bag
left $480 - $192 = $288
1/4 of $288 = $72
Total spent on handbag and dress = $192 + $72 = $264
Total spent on blouses = $488 - $264 = $ $216
Each Blouse = $216/4 = $54
