Sir...how to get 1728 and 1512?

$1512 is given in the question.

Oh. ..yes...I get it now.. each and every question. . I study very hard.. so hard that it is so confusing for me . thanks sir.

You add the first 3 equations together, u will realise that 4 cylinders + 4 diamonds + 4 hearts = 120 So what is 1 cylinder + 1 diamond + 1 heart = ?

Sorry I dun get it

Ok get it thanks to Zhong Shu Hao and Delia Gong Hsien-Ai🙏

120 / 4 = ?

120/4=30 30x3=90

May I know what level is this wn for?

Pri 5

looks like p3 question

My daughter tried to use algebra to solve it. Not sure if it's correct. Hope it helps!

30. Take all 3 equations -> 4 sets = 120. So 1 set = 30

Same same...,

Add every thing then divide by 4 ans is 30

Add all the animals and devide by 2. All the animals were twice on the scale

Ans: 30 Add all up equals to 4 cylinders + 4 diamonds + 4 hearts = 120 Therefore simply divide by 4 to get the last equation

The three smallest possible numbers of cubes Caili may have are 3 × 3 + 8 = 17, 4 × 4 + 8 = 24, and 5 × 5 + 8 = 33

Thank you for your kind advise Raymond and Xavier.

The pleasure is mine, thank you.

Not sure.

Thanks See Yeong and Xavier for your help. It took me a while to understand how it was worked out.

Please let us know if we can provide any form of clarification. Thank you and regards
