150/6 = 25 then square root = 5 then cube it = 125

Cube has 6 surfaces. So 150÷6=25 ~ area of one surface. Square root of 25 is 5. Volume: 5×5×5=125

Since the base area of A is twice the base area of B, the height of A should be half the height of B. Only then will the two cuboids have the same volume. So... Ans: 16cm÷2=8cm

Charlotte paid for the souvenir first.

$6.40 is 2% of $320 So the difference between what Charlotte paid for and Wendy paid for must be 4%. Wendy paid for lodging and transport (48%). Charlotte paid for souvenir and food (52%).
