5. The internal dimension of a tank are 14m, 8m and 5m. How much water can be
EleoNora [17]

Answer:

560,000L

Step-by-step explanation:

Given data

L=14m

W=8m

H=5m

Volume= L*W*H

Volume= 14*8*5

Volume= 560 m^3

1m^3 = 1000L

560m^3 = x

cross multiply

x= 560*1000

x= 560,000L

Hence the volume is  560,000L

Sindrei [870]

Yo sup??

Lenght of two side will be equal to 20 in as its an isoceles triangle.

The third side will be

x^2=b^2+h^2    (by pythagoreas theorem)

=9^2+9^2

x=9√2 in

Therefore the perimeter is = 9+9+9√2

=9√2(√2+1) in

Hope this helps.
