Question

6 cm किनारे वाले घन का पृष्ठीय क्षेत्रफल कितना होगा​

Answer 1

Given :  6 cm किनारे वाले घन

A cube with edge length of 6 cm

To Find : पृष्ठीय क्षेत्रफल

Surface area

Solution:

घन का पृष्ठीय क्षेत्रफल = 6a²

Surface area  of cube =  6a²

a = edge length =  6 cm

a = किनारे की लम्बाई  = 6 cm

घन का पृष्ठीय क्षेत्रफल = 6(6)²  = 216 cm²

Surface area  of cube =  6(6)² = 216 cm²

घन का पृष्ठीय क्षेत्रफल 216 cm² होगा​

Surface area of cube will be  216 cm²
