if the length is 9 cm, breadth is 10 cm and volume of cuboid is 1800cm cube ,,find the height and total surface area of cuboid,​

the height is 20 cm.

tsa is 940 cm square

Step-by-step explanation:

volume of cuboid = l*b*h

1800 = 9*10*h

h= 20 cm

TSA = 2(L*B+ B*H + L*H)

= 2(9*10 + 10*20 + 9*20)

=940 cm square

Step-by-step explanation:

length * breadth * height = volume

plug it in

9 * 10 * height = 1800

height = 1800 ÷ 90

height = 20

2lw+2lh+2hw = surface area

breadth = width = w

plug it in

(2 * 9 * 10) + (2 * 9 * 20) + (2 * 20 * 10) = surface area

940 = surface area

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

if x = 2 you have to find x to finish the problem
