once again I am stumped
Does anyone have the IPS 10 practice papers?
test 3 has a question on surface area. There is a net which folds to make a box. Each square square has sides of 2cm. The net has 4 rectangles 4x 2 squares (so 4cm x 8cm), which are the sides of teh box and 2 squares , the ends) which are 2 squares by 2 squares (so 4cm x4 cm)
It asks for the surface area of the box.
Choices given are
160 cubic centimetres
60 cubic centimetres
120 cubic centimetres
48 cubic centimetres
80 cubic centimetres
answer given is 80 square centimetres.
I worked out area of all the sides and added them, thinkig this would be surface area. no answer matched
then thought it may be volume and a misprint ( given cubic centimetres) still no match.
It is probably right under my nose but I am obsessed now!!
all help gratefully received.
