Question

Cardboard crate is 6dm long 3.4dm and 3dm high find its total surface area in cm square and dm square if the total crate surface is 5/6

Answer 1

Answer:

Explanation:

TSA = 2(lb+ bh + lh)

l=6 d.m.

b=3.4 d.m.

h=3 d.m.

lb =(6 * 3.4) d.m.

   = 20.4 d.m.

bh = (3.4 * 3) d.m.

    = 10.2 d.m.

lh = (6 * 3) d.m.

   = 18 d.m.

TSA =( 2(20.4 + 10.2 + 18) )d.m.

      = (2 * 48.6) d.m.

      = 97.2 $d.m.^{2}$
