he diagonal of a cuboid is 25cm, breadth is 16cm and height is 12 cm.

1.	he diagonal of a cuboid is 25cm, breadth is 16cm and height is 12 cm. Find its length, volume and surface area
Answer» ANSWER: length=15, volume=2880 Step-by-step EXPLANATION: DIAGNOL of CUBOID =√l²+b²+h² 25=√16²+12²+x² squaring on both sides 625=256+144+x² 625-256-144=x² 225=x² √225=x 15=x volume of cuboid=l×b×h ⇒ 15×16×12 ⇒2880

he diagonal of a cuboid is 25cm, breadth is 16cm and height is 12 cm. Find its length, volume and surface area

Answer»

length=15, volume=2880

Step-by-step EXPLANATION:

DIAGNOL of CUBOID =√l²+b²+h²

25=√16²+12²+x²

squaring on both sides

625=256+144+x²

625-256-144=x²

225=x²

√225=x

15=x

volume of cuboid=l×b×h

⇒ 15×16×12

⇒2880
