Question
A rectangular prism has dimensions 10 cm × 6 cm × 4
cm. If a cube of side 2 cm is removed from one of the corners, what is the volume of the remaining solid?Solution
Volume of the rectangular prism = length × width × height = 10 × 6 × 4 = 240 cm³. Volume of the cube = side³ = 2³ = 8 cm³. Remaining volume = Volume of the prism - Volume of the cube = 240 - 8 = 232 cm³. Correct option: b) 232 cm³
Evaluate:
√729 + √49 - √16 + 1/√64
Simplify:

(1/5)(40% of 800 – 120) = ? × 5
2/5 of 3/4 of 7/9 of 7200 = ?
`sqrt(5476)` + 40% of 1640 = ? `xx` 4 - 2020
? = (22% of 25% of 60% of 3000) + 21
Determine the simplified value of the given mathematical expression.
(342 – 20% of 5280) = ? ÷ 3
∛157464 =?
