Final answer:
We cannot determine the amount of white cloth needed for 35 sets of grade school uniforms without knowing the amount of cloth required for one set. Additional information is needed to perform the calculation.
Step-by-step explanation:
To determine how much white cloth is required for 35 sets of grade school uniforms, we need to know the amount of cloth required for one set of uniform.
Unfortunately, this information is not provided in the question, hence we are unable to calculate the total amount of cloth needed for 35 sets of uniforms. Without the measurement for one set, it's not possible to multiply that amount by 35 to find the total required cloth. If additional information is provided, such as the amount of white cloth needed for one uniform, we could then perform the calculation to find the correct answer.
