Answer:
The surface area is 248 square inches
Step-by-step explanation:
The missing dimensions (that complete the question) are:
[tex]Length = 4\ in[/tex] --- L
[tex]Width = 6\ in[/tex] ---- W
[tex]Height =10\ in[/tex] --- H
Required:
Calculate the surface area
The surface area is:
[tex]Area = 2(L*W + L*H + H*W)[/tex]
Substitute values for L, W and H
[tex]Area = 2(4*6+ 4*10 + 10*6)[/tex]
[tex]Area = 2(24+ 40 + 60)[/tex]
[tex]Area = 2(124)[/tex]
Remove bracket
[tex]Area = 2*124[/tex]
[tex]Area = 248[/tex]
