Question

Two cubes each of side 4cm are joined end to end. Find the surface area of tje resulting cuboid

Answer 1

Answer:

Step-by-step explanation:

Here a answer

T S A of cuboid= 2(5a^2)

=2(5*16)

=160

Answer 2

For the resulting cube:

l = 4 + 4 = 8cm

b = 4cm

h = 4cm

$\therefore$ $\sf\red{Surface\:area\:of\: the\:resulting\:cuboid}$

$\longrightarrow$$\sf\purple{2(lb+bh+hl)}$

$\longrightarrow$$\sf\purple{2(8×4+4×4+4×8){cm}^{2}}$

$\longrightarrow$$\sf\purple{2(32+16+32){cm}^{2}}$

$\longrightarrow$$\sf\purple{{160cm}^{2}}$
