Volume= 1/3( 10*24*13)=1040 cubic units.
To find surface area slant ht is required.
Let slant ht attached to sides 10 and 24 are h1 and h2.
h1 = √(12^2+13^2)= 17.69 units.
Surface area of slant surfaces attached to side 10 is = 1/2(10*17.69)*2 ( for two identical opposite surfaces))
=176.9 sq units.
Similarly h2 =√(5^2+13^2)= 13.93 units.
Surface area of slant surfaces attached to side 24 is= 1/2(24*13.93)*2= 334.32 sq units.
Total surface area = 176.9+334.32=511.22 sq units 2
