Below are sample questions representative of the exercises included on this worksheet and related GEO.11 Use estimation and bounds to validate answers skill assessments:

Problem 1Difficulty: Mastery

A cube has total surface area 750 cm². A student claims the side length is about 11 cm. Which bound best verifies whether 11 cm is reasonable?

ASince 750÷3 = 250, the side is between 15 and 16

BSince 750÷12 = 62.5, the side is between 7 and 8

CSince 11³=1331, the side must be 11

DSince 750÷6 = 125 and 11²=121 < 125 < 12²=144, the side is between 11 and 12

Solution & Explanation:For a cube, SA=6s², so s=√(SA ÷ 6)=√125. Because 125 is between 121 and 144, √125 is between 11 and 12.

Problem 2Difficulty: Mastery

A semicircular window has diameter 1.2 m. A student computed the glass area as 0.57 m². Using 3.1 < π < 3.2, which interval must contain the true area?

ABetween 0.40 and 0.45

BBetween 0.50 and 0.55

CBetween 0.558 and 0.576

DBetween 0.60 and 0.65

Solution & Explanation:Radius is 0.6 m. Semicircle area is 0.5πr²=0.5π(0.36)=0.18π. With 3.1<π<3.2, area is between 0.558 and 0.576 m².

Problem 3Difficulty: Mastery

A shape is scaled by a factor of 0.75. A student says both perimeter and area become 75% of the original. Which estimate best checks the correct area factor?

AArea factor should be 0.75 (75%)

BArea factor should be 0.75² = 0.5625 (about 56%)

CArea factor should be 0.75³ ≈ 0.42

DArea factor should be 1−0.75 = 0.25

Solution & Explanation:Perimeter scales by 0.75, but area scales by the square: 0.75²=0.5625, so area is about 56% of the original.
