​

Answer 1

Answer. Area of (4 walls + ceiling )

=(2hl+2bh)+lb

=2×(2×1.5)+2×(1×1.5)+(2×1)

=2×3+2×1.5+2

=6+3+2

=11.

.

Answer 2

AREA OF CUBIOD =

$2(hb + hl + lb)$

AREA OF CUBIOD PAINTED (not cover top and bottom face) =

$2(hb + hl) \\ = 2(1.5 \times 2 + 1.5 \times 1) \\ = 2(4.5) \\ = 7 \: {m}^{2}$

Note- h= 1.5m , b=1 m, l= 2m

THEREBY THE AREA PAINTED IS 7 sq. m
