A rectangular prism has volume 288 cm³ and base dimensions 6 cm and 4 cm. Find its height.
10 cm
11 cm
12 cm
13 cm
Answer: C
Solution: Volume \(=\text{length}\times\text{breadth}\times\text{height}\). Thus, \(288=6\times4\times h\). So, \(h=\frac{288}{24}=12\) cm. Trick: Divide the volume by the area of the rectangular base.
एक आयताकार प्रिज्म का आयतन 288 सेमी³ है और आधार की विमाएँ 6 सेमी तथा 4 सेमी हैं। इसकी ऊँचाई ज्ञात कीजिए।
10 सेमी
11 सेमी
12 सेमी
13 सेमी
उत्तर: C
हल: आयतन \(=\text{लंबाई}\times\text{चौड़ाई}\times\text{ऊँचाई}\)। इसलिए \(288=6\times4\times h\)। अतः \(h=\frac{288}{24}=12\) सेमी। ट्रिक: आयतन को आयताकार आधार के क्षेत्रफल से भाग दें।
