Question 1059101
Let {{{ a }}} = the area in ft2 of one of the sides
Let {{{ b }}} = the area of top or the bottom in ft2
-------------------------------------------
(1) {{{ 4a + 2b = 10 }}}
(2) {{{ a = 2b }}}
-----------------------
Plug (2) into (1)
(1) {{{ 4*(2b) + 2b = 10 }}}
(1) {{{ 8b + 2b = 10 }}}
(1) {{{ 10b = 10 }}}
(1) {{{ b = 1 }}}
and
(2) {{{ a = 2b }}}
(2) {{{ a = 2*1 }}}
(2) {{{ a = 2 }}}
-------------------
The area of each of the side faces is 2 ft2
The area of top is 1 ft2
The area of the bottom is 1 ft2
