Question

7. The base area of a cuboid of height 7 m is 90 m²,
find the volume of the cuboid.​

Answer 1

Answer:

Step-by-step explanation:

et the height of a cuboid is h m

Given the length of a cuboid is 6 m

The breadth of a cuboid is 5 m

Total surface area of a cuboid is 126 m  

2

 

⟹2(5×6+5×h+6×h)=126

⟹30+11h=63

⟹11h=33

⟹h=  

11

33

​  

=3

So the height of a cuboid is 3 m

Answer 2

Step-by-step explanation:

base area mean length * breadth is given 90

volume : l*b*h

90* 7

= 630 cubic meter
